2e2655f1 - [AMDGPU] Require flushed FP16 denormals for the mad-mix f16 results (#224911)

[AMDGPU] Require flushed FP16 denormals for the mad-mix f16 results (#224911) v_mad_mixlo_f16 and v_mad_mixhi_f16 are the unfused gfx900 forms and flush 16-bit denormals, so a denormal half result is written as zero even when the FP16 mode asks for it to be kept, while the patterns only required the FP32 mode to flush and that is the one a HIP compile turns off on its own.
