Jay Foad 43b9888214 [AMDGPU] Use nan as the identity for atomicrmw fmax/fmin (#97411) ...

atomicrmw fmax/fmin perform the same operation as llvm.maxnum/minnum
which return the other operand if one operand is nan. This means that,
in the presence of nan arguments, +/- inf is not an identity for these
operations but nan is (at least if you don't care about nan payloads).
