  Log Message:
  -----------
  AMDGPU: Don't canonicalize fminnum/fmaxnum if targets support IEEE fminimum(maximum)_num (#127711)

  For targets that support IEEE fminimum_num/fmaximum_num, the
corresponding *_min_num_fXY/*_max_num_fXY instructions themselves
already did the canonicalization for the inputs. As a result, we do not
need to explicitly canonicalize the inputs for fminnum/fmaxnum.
