[llvm-branch-commits] [clang] [HLSL] Use memcpy for HLSL buffer copies that don't have padding (PR #173093)

I think this can cause issues in the spirv backend. I believe some optimizations will replace short memcopy with a load and store of integers regardless of the actual type of the memory. That does not translate well to spirv.
