/* Enable 64-bit and 16-bit denormals, because there is no performance
* cost.
*
* If denormals are enabled, all floating-point output modifiers are
* ignored.
*
* Don't enable denormals for 32-bit floats, because:
* - Floating-point output modifiers would be ignored by the hw.
* - Some opcodes don't support denormals, such as v_mad_f32. We would
* have to stop using those.
* - GFX6 & GFX7 would be very slow.
