3e97b5d0 - [IR] Make @llvm.memset prototype byte width dependent

[IR] Make @llvm.memset prototype byte width dependent This patch changes the type of the value argument of @llvm.memset and similar intrinsics from i8 to iN, where N is the byte width specified in data layout string. Note that the argument still has fixed type (not overloaded), but type checker will complain if the type does not match the byte width. Ideally, the type of the argument would be dependent on the address space of the pointer argument. It is easy to do this (and I did it downstream as a PoC), but since data layout string doesn't currently allow different byte widths for different address spaces, I refrained from doing it now.
