This is the patch to provide clean intrinsic function overloading support in LLVM. It cleans up the intrinsic definitions and generally smooths the process for more complicated intrinsic writing. It will be used by the upcoming atomic intrinsics as well as vector and float intrinsics in the future.
...
This also changes the syntax for llvm.bswap, llvm.part.set, llvm.part.select, and llvm.ct* intrinsics. They are automatically upgraded by both the LLVM ASM reader and the bitcode reader. The test cases have been updated, with special tests added to ensure the automatic upgrading is supported.

For PR1297:
...
Implement code generation for overloaded intrinsic functions. The basic
difference is that "actual" argument types must be provided when
constructing intrinsic names and types. Also, for recognition, only the
prefix is examined. If it matches, the suffix is assumed to match. The
suffix is checked by the Verifier, however.

...
#include <mmintrin.h>
extern __m64 C;
void baz(__v2si *A, __v2si *B)
{

_mm_empty();
}
We get this:
_baz:

"L1$pb":
popl %eax
movl L_C$non_lazy_ptr-"L1$pb"(%eax), %eax
movq (%eax), %mm0

movq %mm0, (%eax)

"L00000000001$pb":
L3:
popl %ebx
subl $8, %esp
movl L_C$non_lazy_ptr-"L00000000001$pb"(%ebx), %eax
