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.
