nir: allow sat on all float destination types

Browse source 
With the introduction of fp64 and fp16 to nir, there are now a bunch of
float types running around. A F1 2015 shader ends up with an i2f.sat
operation, which has a nir_type_float32 destination. Allow sat on all
the float destination types.
