[PATCH] nv50/ir: avoid creating instructions that can't be emitted
When constant folding a MAD operation, we first fold the multiply and
generate an ADD. However we do so without making sure that the immediate
can be handled in the saturate case. If it can't, load the immediate in
a separate instruction.
