5a63b2100e More consistent use of backticks and "expected" in error messages. 
Got some of the debug messages, here, too.  I figure it doesn't hurt
to get used to doing this even in places where users won't ever see
it.

f39477d926 In resolve, check that an or-pattern has the same number of bindings in each disjunct 
resolve3 wasn't checking this. Added test cases. Also added a helpful informational
message in the case where you have a variable binding that you probably think
refers to a variant that you forgot to import.

This is easier to do in resolve than in typeck because there's code in typeck
that assumes that each of the patterns binds the same number of variables.

697f1e38d6 Change 'native' and 'crust' to 'extern'. 
This comes with a terminology change. All linkage-symbols are 'extern'
now, including rust syms in other crates. Some extern ABIs are
merely "foreign". The term "native" is retired, not clear/useful.

What was "crust" is now "extern" applied to a _definition_. This
is a bit of an overloading, but should be unambiguous: it means
that the definition should be made available to some non-rust ABI.

cc323d8637 Make liveness print out a proper error message for moves out of a self field 
This was a call to span_bug() before. I'm not sure about the other cases,
but the test case shows that the `vk_self` case can certainly arise with
a bad program, so it should be a span_err() thing and not a span_bug() thing.

0327dc0b18 Insert missing maybe_print_comment call for class destructors 
While it wasn't the original issue, the first program from #2487
failed the pretty-printing test because of this, so it's still a good
test case :-)

It also turns out that the second program from #2487 now triggers a
kind error, so I figured I might as well add it as a test case.

  - we never checked that iface types were compatible when casting
    to an iface with `as`
  - we allowed nonsense like int<int>
  - and more! (actually that may be it)

In the "not all paths return" error message, typestate was printing

when the AST return type was "ty_infer". Now it looks up the function node
ID's type and uses util::ppaux::ty_to_str instead.

5c12cd72f4 Allow classes to implement ifaces 
Introduce syntax like:

to allow classes to implement ifaces. Casting classes to ifaces
is *not* yet supported. ifaces that a class implements are not
yet included in metadata.

The syntax is subject to change, and may go away completely if we
decide to use duck typing to relate classes with ifaces (see
http://smallcultfollowing.com/babysteps/blog/2012/04/10/declared-vs-duckish-typing/ )

87b064b249 First stab at operator overloading 
When no built-in interpretation is found for one of the operators
mentioned below, the typechecker will try to turn it into a method
call with the name written next to it. For binary operators, the
method will be called on the LHS with the RHS as only parameter.

Binary:

    +   op_add
    -   op_sub
    *   op_mul
    /   op_div
    %   op_rem
    &   op_and
    |   op_or
    ^   op_xor
    <<  op_shift_left
    >>  op_shift_right
    >>> op_ashift_right

Unary:

    -   op_neg
    !   op_not

Overloading of the indexing ([]) operator isn't finished yet.

9dc59e1506 Export all enum variants by default; new syntax for selectively exporting variants 
See issue 1426 for details. Now, the semantics of "export t;" where t is a tag are
to export all of t's variants as well. "export t{};" exports t but not its
variants, while "export t{a, b, c};" exports only variants a, b, c of t.

To do:
- documentation
- there's currently no checking that a, b, c are actually variants of t in the
 above example
- there's also no checking that t is an enum type, in the second two examples above
- change the modules listed in issue 1426 that should have the old export
semantics to use the t{} syntax

I deleted the test export-no-tag-variants since we're doing the opposite now,
and other tests cover the same behavior.

7c7559edaf Disallow variable names that shadow tags in scope 
Now, if you have a tag named "foo", a variable declaration like
"let foo..." is illegal. This change makes it possible to eliminate
the '.' after a nullary tag pattern in an alt (but I'll be doing
that in a future commit) -- as now it's always obvious whether a
name refers to a tag or a new declared variable.

resolve implements this change -- all the other changes are just to
get rid of existing code that declares variables that shadow tag
names.

I think it should undefined to have multiple modules that link in the same

link_args by module -- they are just appended as discovered into the crate

3e303af86b rustc: Add a path attribute for crate directives 
The path information was an optional "filename" component of crate
directive AST. It is now replaced by an attribute with metadata named
"path".

With this commit, a directive

  mod foo = "foo.rs";

should be written as:

  #[path = "foo.rs"]
  mod foo;

Closes issue #906.

f6491bb426 Update stdlib, compiler, and tests to new kind system 
This involved adding 'copy' to more generics than I hoped, but an
experiment with making it implicit showed that that way lies madness --
unless enforced, you will not remember to mark functions that don't
copy as not requiring copyable kind.

88f29aab27 Use attributes for native module ABI and link name 
This patch changes how to specify ABI and link name of a native module.

Before:
  native "cdecl" mod llvm = "rustllvm" {...}

After:
  #[abi = "cdecl"]
  #[link_name = "rustllvm"]
  native mod llvm {...}

The old optional syntax for ABI and link name is no longer supported.

9ff6f816ba Fix handling of loops and conditionals in alias.rs 
It now threads information about invalidated aliases through the AST
properly. This makes it more permissive for conditionals (invalidating
an alias in one branch doesn't prevent you from using it in another),
and less permissive for loops (it now properly notices when a loop
invalidates an alias that it might still use in another iteration).

too, when they refer to a local outside the body.

722fa00681 Get rid of the hack that ignores () typed things in fn tail position. 
Closes #868. Unfortunately, this causes certain invalid programs to
fail type-checking instead of failing type-state when a type-state
error message would probably be more intuitive. (Although, by any
reasonable interpretation of the static semantics, it technically
ought to be a type error.)

Autoderef on binops is basically unused, kind of silly, and

foo + 1", which should be written as "*foo += 1" anyways.

1c786bcc82 Initialize all constraints to False 
Previously, typestate was initializing the init constraint for
a declared-but-not-initialized variable (like x in "let x;") to False,
but other constraints to Don't-know. This led to over-lenient results
when a variable was used before declaration (see the included test
case). Now, everything gets initialized to False in the prestate/poststate-
finding phase, and Don't-know should only be used in pre/postconditions.

This aspect of the algorithm really needs formalization (just on paper),
but for now, this closes #700

In the writeback phase, the typechecker now checks that it isn't

getting into an infinite chain of derefs.

I'm a bit worried that there are more places where the occurs
check needs to happen where I'm not doing it now, though.

5cf5f5024d Handle bang functions correctly in typestate 
The logic for how the "returns" constraint was handled was always
dodgy, for reasons explained in the comments I added to
auxiliary::fn_info in this commit. Fixed it by adding distinct
"returns" and "diverges" constraints for each function, which
are both handled positively (that is: for a ! function, the
"diverges" constraint must be true on every exit path; for
any other function, the "returns" constraint must be true
on every exit path).

2573fe7026 The Big Test Suite Overhaul 
This replaces the make-based test runner with a set of Rust-based test
runners. I believe that all existing functionality has been
preserved. The primary objective is to dogfood the Rust test
framework.

A few main things happen here:

1) The run-pass/lib-* tests are all moved into src/test/stdtest. This
is a standalone test crate intended for all standard library tests. It
compiles to build/test/stdtest.stageN.

2) rustc now compiles into yet another build artifact, this one a test
runner that runs any tests contained directly in the rustc crate. This
allows much more fine-grained unit testing of the compiler. It
compiles to build/test/rustctest.stageN.

3) There is a new custom test runner crate at src/test/compiletest
that reproduces all the functionality for running the compile-fail,
run-fail, run-pass and bench tests while integrating with Rust's test
framework. It compiles to build/test/compiletest.stageN.

4) The build rules have been completely changed to use the new test
runners, while also being less redundant, following the example of the
recent stageN.mk rewrite.

It adds two new features to the cfail/rfail/rpass/bench tests:

1) Tests can specify multiple 'error-pattern' directives which must be
satisfied in order.

2) Tests can specify a 'compile-flags' directive which will make the
test runner provide additional command line arguments to rustc.

There are some downsides, the primary being that Rust has to be
functioning pretty well just to run _any_ tests, which I imagine will
be the source of some frustration when the entire test suite
breaks. Will also cause some headaches during porting.

Not having individual make rules, each rpass, etc test no longer
remembers between runs whether it completed successfully. As a result,
it's not possible to incrementally fix multiple tests by just running
'make check', fixing a test, and repeating without re-running all the
tests contained in the test runner. Instead you can filter just the
tests you want to run by using the TESTNAME environment variable.

This also dispenses with the ability to run stage0 tests, but they
tended to be broken more often than not anyway.

bd4aeef78b Beginnings of support for constrained types 
Programs with constrained types now parse and typecheck, but
typestate doesn't check them specially, so the one relevant test
case so far is XFAILed.

Also rewrote all of the constraint-related data structures in the
process (again), for some reason. I got rid of a superfluous
data structure in the context that was mapping front-end constraints
to resolved constraints, instead handling constraints in the same
way in which everything else gets resolved.

21b94d57d5 Change typestate to use visit instead of walk 
Typestate was failing to check some code because if it saw an item,
it would quit immediately. This was to avoid checking nested items
in the same context as the lexically enclosing item, but it was
having the wrong effect: not checking the code after the item at all.

Fixed by switching to visit and skipping over items in a proper
nested fashion. Closes #668.

e1620def9f In typeck, check for dynamically sized by-value arguments to thunks 
A check in trans didn't have a corresponding check in typeck, causing
some programs (to wit, compile-fail/chan-parameterized-args.rs - part of this
commit) to fail with an assertion failure in trans instead of a type error.
Fixed it. In short, arguments that are future thunk arguments (any spawn
arguments, and _ arguments in bind) need to either not contain type params
or type vars, or be by-reference.
