08abf8d37f Support explicit discriminant numbers on tag variants.
Addresses issue #1393.

For now disallow disr. values unless all variants use nullary
contractors (i.e. "enum-like").

Disr. values are now encoded in the crate metadata, but only when it
will differ from the inferred value based on the order.

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.

f4acaf6934 Only look for a matching method when normal field access fails

f14bc54b06 allow #[link_args] with #[nolink]. For now, fail if two modules link same lib, and second has link_args.
I think it should undefined to have multiple modules that link in the same
library, but provide different link arguments. Unfortunately we don't track
link_args by module -- they are just appended as discovered into the crate
store -- but for now, it should be an error to provide link_args on a module
that's already been included (with or without link_args).

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;

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).

f8a35234ad Remove autoderef for calls
We were only using it in a single place, and there for no discernable reason
(probably as part of the bare-fn-vals-are-not-copyable plan). It seems more

It is now 1-based, rather than 0 based. (Seems more natural, and allows 0 to

be5537e95f Be more strict about what constitutes a block expression
Blocks (or statements involving blocks) that end in a semicolon are no
longer considered the block-expression of their outer block. This used
to be an expression block, but now is a statement block:

    { if foo { ret 1; } else { ret 10; } }

This helps clear up some ambiguities in our grammar.

6ba4eacddf Make resolve recognize upvars
Upvars are now marked with def_upvar throughout, not just when going
through freevars::lookup_def. This makes things less error-prone. One
thing to watch out for is that def_upvar is used in `for each` bodies
too, when they refer to a local outside the body.

2d1dec78e7 Move mutability checking into its own pass.
Having it in the alias pass was slightly more efficient (finding
expression roots has to be done in both passes), but further muddled
up the already complex alias checker.

Also factors out some duplication in the mutability-checking code.

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.)

0340f32748 Eliminate autoderef on binops and unary negation.
Autoderef on binops is basically unused, kind of silly, and

compiler and the test drivers, two of which were of the form "*foo =
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

2baaeab784 Implement the occurs check
In the writeback phase, the typechecker now checks that it isn't
replacing a type variable T with a type that contains T. It
also does an occurs check in do_autoderef in order to avoid
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.

Closes #768
