e2e077c831 Remove trivial cast checker 
I consider the added complexity not justified at this point, and it
interacts badly with the patches for issue #828. Feel free to discuss.

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.

4e03112141 Add a pass-by-copy parameter passing convention 
This is intended to solve the problem of how to pass arguments to
constructor functions -- you want to move in rvalues, but not have to
explicitly copy stuff that is not an rvalue. The by-copy passing
convention will ensure the callee gets its own copy of the value. For
rvalues, it'll just pass off the value. For lvalues, it'll make a
copy.

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.

7dacccde94 Make shared kind the default only for generic functions 
You almost never want a function with pinned type params. For

more sane. For most of these, shared rarely makes sense. Only tricky
case is objs -- you'll have to think about the kinds you want there.

b0a72ee06a Be more careful when parsing block calls 
Previously, the parser would try to interpret this as a block call:

    if true {} // No semicolon

7114702496 Change the way block calls are parsed, mark them as block-calls. 
This makes it possible to omit the semicolon after the block, and will
cause the pretty-printer to properly print such calls (if
pretty-printing of blocks wasn't so broken). Block calls (with the
block outside of the parentheses) can now only occur at statement
level, and their value can not be used. When calling a block-style
function that returns a useful value, the block must be put insde the
parentheses.

0714bb5f7d Fix the problem with check-fast randomly failing 
Trans has been assuming that tag node id's are unique across crates and they
are not so, depending on which way the wind is blowing, it would choose to use
a crate-local tag variant instead of the correct one from std.

No test case since I can't come up with a reliable one that compiles in a
reasonable amount of time.

Patch to error and fail instead of using all available memory
then crashing to detect the error condition of an unmatched
double quote before the end of a file.

I couldn't get it to show nice error messages, so this may not be
the ideal fix.

- An expression that ends* in a block without trailing expression can
  can not be called, indexed, or subscripted.

- Only expression-statements that end* in a block without trailing
  expression can omit their semicolon.

*) 'Ending in a trailing expression' is defined as being a block or
   construct-ending-in-a-block (if, alt) that either ends in an
   expression itself, or ends in another block-like expression that
   has a trailing expression (by these same rules).

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.
