  Log Message:
  -----------
  AMDGPU: Start selecting flat/global atomicrmw fmin/fmax. (#95592)

Define subtarget features for atomic fmin/fmax support.

The flat/global support is a real messe. We had float/double support at
the beginning in gfx6 and gfx7. gfx8 removed these. gfx10 reintroduced them.
gfx11 removed the f64 versions again.

gfx9 partially reintroduced them, in gfx90a and gfx940 but only for f64.
