[PATCH] Mangling for intrinsic names w/function type parameters

[Andrew Trick]

I might be missing something. But I think that LLVM should have a small finite number of intrinsics for patchpoint, and the frontend (JIT client) should be able to pass it a symbolic target with any signature. In other words, we should always treat the target arguments as varargs from the intrinsic's point of view. That doesn't change the actual calling convention used.
