This matches other assemblers and is less unexpected (e.g. PR23227). On ELF, I tried binutils gas v2.24 and nasm 2.10.09, and they both agree on LShr. On COFF, I couldn't get my hands on an assembler yet, so don't change the behavior. For now, don't change it on non-AArch64 Darwin either, as the other assembler is gas v1.38, which does an AShr. llvm-svn: 235963
