Matt Arsenault 982ff7f443 AMDGPU: Improve nsw/nuw/exact when promoting uniform i16 ops ...

These were simply preserving the flags of the original operation,
which was too conservative in most cases and incorrect for mul.

nsw/nuw may be needed for some combines to cleanup messes when
intermediate sext_inregs are introduced later.

Tested valid combinations with alive.
