698c6406ba Reject programs with unsatisfied predicate constraints
Generate appropriate constraints for calls to functions with
preconditions, and reject calls where those constraints don't
hold true in the prestate.

...by which I mean that it works for one test case :-)

52c4c9014f Encode meta tags in the crate and start sketching enhanced logic for resolving crate "use" directives.
Now with extra "works on OSX" kludging.

fccf065266 Implement mutable/immutable alias distinction.
Before, all aliases were implicitly mutable, and writing
&mutable was the same as writing &. Now, the two are
distinguished, and assignments to regular aliases are
no longer allowed.

17ff2a0d79 Further support for predicate constraints
Changed function types to include a list of constraints. Added
code for parsing and pretty-printing constraints. This necessitated
splitting pprust into two files (pprust and ppaux) to break a
circulate dependency, as ty_to_str now needs to print out constraints,
which may include literals, but pprust depended on ty.

ddec6b5f47 rustc: Use a set-based approach to unification; remove ty_bound_param and ty_local.
Sorry, big perf regression; will fix soon.

a08a376d6e Make controlflow part of a function type
Change ty_fn to have a controlflow field. A 'controlflow' is
essentially a bit of data that says whether or not this function
never returns to the caller (if it never returns, that means it calls
"fail" or another "never-returns" function on every control path).

Also add syntax for annotating functions that never return:

fn foo() -> ! {
   fail;
}

for example. Functions marked with ! implicitly have a result type of
ty_bot, which is a new type that this commit also adds.

e9c12ab1d0 Rewrite comp/middle/resolve.rs
* Cleans up the algorithm
 * Move first pass to walk (second still folds)
 * Support part of a type/value namespace split
   (crate metadata and module indices still need to be taught about this)
 * Remove a few blatant inefficiencies (import tables being recreated for
   every lookup, most importantly)

aa25f22f19 Use different syntax for checks that matter to typestate
This giant commit changes the syntax of Rust to use "assert" for
"check" expressions that didn't mean anything to the typestate
system, and continue using "check" for checks that are used as
part of typestate checking.

Most of the changes are just replacing "check" with "assert" in test
cases and rustc.

d678dad434 Fix problem in metadata writer
It was creating non-multiple-of-four section sizes, which, for some
reason, presumably by LLVM, were clipped, rather than padded, to be a
