aeea2e7c1f nir: add fmad_or_ffma helpers and use it in lower_double_ops 
We skip emitting ffma_weak here, because otherwise we'd require a lowering
loop with opt_algebraic and lower_double_ops and this way it's also
cheaper.

eb817b1f63 virgl: advertise new muladd options 
The "old" nir_to_tgsi_compiler_options enabled fusing for 32 and 64 bit,
and virglrenderer implements TGSI's MAD as an mul+add. But because virgl
also lowered it for 32 bits, we just enable fmad for 64 bit.
