Tim Northover 19c8a66443 AArch64: allow MOV (imm) alias to be printed
The backend has been around for years, it's pretty ridiculous that we can't
even use the preferred form for printing "MOV" aliases. Unfortunately, TableGen
can't handle the complex predicates when printing so it's a bunch of nasty C++.
Oh well.

; We actually need to use -filetype=obj in this test because if we output
; assembly, the current code path will bypass the parser and just write the
; raw text out to the Streamer. We need to actually parse the inlineasm to
; demonstrate the bug. Going the asm->obj route does not show the issue.
