Matt Arsenault 2e2bbcacf8 AMDGPU/GlobalISel: Start legalizing minimumnum and maximumnum (#140900) ...

This is the bare minimum to get the intrinsic to compile for AMDGPU,
and it's not optimal. We need to follow along closer with the existing
G_FMINNUM/G_FMAXNUM with custom lowering to handle the IEEE=0 case
better.

Just re-use the existing lowering for the old semantics for
G_FMINNUM/G_FMAXNUM. This does not change G_FMINNUM/G_FMAXNUM's
treatment,
nor try to handle the general expansion without an underlying min/max
variant (or with G_FMINIMUM/G_FMAXIMUM).
