This (work in progress) diff adds three new attributes to clang (__attribute__((LLVMFN(string))), __attribute__((LLVMARG(paramidx, string))), __attribute__((LLVMRET(paramidx, string))) ) for passing attributes down to LLVM.

This is useful for allowing users, tools, or test cases to specify LLVM attributes that may not have a representation in clang.
