miyuki added a dependency: D44460: [ARM] Fix a check in vmov/vmvn immediate parsing.

Currently the LLVM MC assembler is able to convert e.g.

  vmov.i32 d0, #0xabababab

(which is technically invalid) into a valid instruction

  vmov.i8 d0, #0xab

this patch adds support for vmov.i64 and for cases with the resulting
load types other than i8, e.g.:

  vmov.i32 d0, #0xab00ab00 ->
  vmov.i16 d0, #0xab00
