Try to implement the handling of MOVD as attempted in checkin:
70712c0df6
and reverted in:
d279fbbd80
due to BR3392199. This time make sure to use the SX flag to only
match when a size is explicitly given, and also don't duplicate the 0F
6F/7F opcodes, which are documented as MOVQ by AMD as well as Intel.
