64ce092c27 Allow literal patterns to contain arbitrary literal expressions
This removes the need for the unary minus hacks, and allows some other
neat things like matching on 1 >> 4.

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.

05b2cb8ecc rustc: Accepts path attributes for crate directives
Temporarily allow path specified in either as attribute or in AST, like:

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

This is a transitional commit to avoid creating a stage1 snapshot.

2253ed5d1c rustc: Fix position of diagnostic highlight lines
Diagnostic highlight lines are incorrect placed when the related line
number is 10, 100, etc.

The root cause is line number are treated as 0 based (should be 1 based)
when calculating offset of line number digits.

9fb3719ded Rollback return-by-reference
It's proving too inflexible, so I'm ripping out the extra complexity
in the hope that regions will, at some point, provide something
similar.

a8dd52ed36 Remove last traces of auth keyword
The reference now has an empty hole where the auth keyword used to be.
Changing the keyword table seems to require manually sorting the
keywords and putting them back into some kind of arcane interleaved
order. I'll open an issue to actually fix this.

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.

cefff237bf Make tag, resource and object constructors take their arguments by copy
Doing something like some([1, 2, 3]) will now no longer create a temporary
copy of the vector. It will also be easier for the kind checker to see that
putting a resource into a data-structure constructor is safe.

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.

9cf48d3753 Preparation for kind system overhaul
