R600: Change UDIV/UREM to UDIVREM when legalizing types
When legalizing ops, with UDIV/UREM set to expand, they automatically
expand to UDIVREM (if legal or custom).
We need to do this manually for legalize types.
v2:
SI should be set to Expand because the type is legal, and it is
automatically lowered to UDIVREM if UDIVREM is Legal/Custom
R600 should set to UDIV/UREM to Custom because it needs to lower them
during type legalization
