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. llvm-svn: 272865

; assembly, the current code path will bypass the parser and just write the
