[LLVMdev] GHC, aliases, and LLVM HEAD

I still have the same objections to having alias to declarations when
they are not supported in the object file. Since they are not
supported in the object file, they must be removed somewhere along the
way and it is not clear the burden should be in the LLVM to Obj
transition instead of in the transition from c-- to llvm.

It is also still not clear why you need aliases at all. LLVM has
declarations and bitcasts, so like c-- it is not type safe, but unlike
c-- (from your description) casts are needed.
