  CodeGen: Strengthen definition of F{MIN|MAX}NUM_IEEE nodes (#85195)

Previously these were declared as having the 2008 behavior, with
underspecified signed zero handling. Currently, AMDGPU, PPC and
LoongArch mark these as legal. The AMDGPU and PPC instructions respect
the signed zero behavior. The LoongArch documentation doesn't state, but
I'm assuming it also does.
