  -----------
  AMDGPU: Partially fix not respecting dynamic denormal mode

The most notable issue was producing v_mad_f32 in functions with the
dynamic mode, since it just ignores the mode. fdiv lowering is still
somewhat broken because it involves a mode switch and we need to query
the original mode.
