021134fdb6 [MC] Use LShr for constant evaluation of ">>" on non-arm64 darwin.
Follow-up to r235963: this matches other assemblers and is less
unexpected (e.g. PR23227).

b4ed01b89b [MC] Use LShr for constant evaluation of ">>" on ELF/arm64--darwin.
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.
