Canonicallize on the non-suffixed form, but continue to accept assembly that
has any correctly sized type suffix.

When widening a copy, we are reading a larger register that may not be
live. Use an <undef> flag to tell the register scavenger and machine
code verifier that we know the value isn't defined.
We now widen:
%S6<def> = COPY %S4<kill>, %D3<imp-def>
into:
%D3<def> = VMOVD %D2<undef>, pred:14, pred:%noreg, %S4<imp-use,kill>
This also keeps the <kill> flag on %S4 so we don't inadvertently kill a
live value in %S5.
Finally, ensure that ARMBaseInstrInfo::setExecutionDomain() preserves
the <undef> flag when converting VMOVD to VORR.
