I'm working on `try_trait_v2` which will break this, so I'm going around removing uses from the rustc tree where I can.

llvm::mk_object_file should really return an option, since the underlying LLVM function can fail. Fixes a crash on OS X when rust has bad dylibs within eyeshot.
Probably other functions throughout the llvm bindings should also have option types returned when they could potentially return null from LLVM -- but this is at least enough to fix a crash in which a "bad" dylib (i.e., one that LLVM can't parse) causes rustc to crash.
