2e8afc7b47 Merge pull request #404 from lkuper/cleanup 
Just removing some unnecessary imports.

fbc0e840e3 Stop showing a 'cyclic import' message for unresolved imports 
This only happened for single-length import paths, because the import
was being looked up in its own scope.

bad05e20a3 Improve nonexistent-module error message 
The error message for (for example) "import vec;" without "use std;"
was "cyclic import", which was misleading because there were no
cycles. I changed it to "cyclic import or nonexistent module",
which doesn't break existing tests.

c9a8bdee2f Improve error message for ambiguous polymorphic types 
If a type still contains free type variables after typechecking (for
example, as with "auto foo = []", the result was an assertion failure
in typeck. Made it a human-readable error message instead.

b620be9cd2 Typecheck @[] correctly 
Previously, if you wrote
let @vec[int] foo = @[];

that would be a type error. That didn't seem right, so I changed
pushdown to unify the inner type in an unop application with the
argument type of the operator type.

2505a2312e rustc: Run the llvm verifier pass before optimization. Closes #376 
The optimization passes were hiding some codegen errors so now we run the
verifier both before and after optimization.

to the pretty-printer.

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.

8cbdaf4f93 Make trans use span_err for the dreaded "ty_var in trans::type_of" error
