r300: remove some late NIR passes

Browse source 
Some of those are no longer needed after moving the sin/cos input fixups
to finalize_nir, while others were are just some unneeded remnants from
nir_to_tgsi era.

Almost no shader-db change on RV530:
total instructions in shared programs: 128940 -> 128939 (<.01%)
instructions in affected programs: 154 -> 153 (-0.65%)

HURT: 2
total cycles in shared programs: 197402 -> 197401 (<.01%)
cycles in affected programs: 263 -> 262 (-0.38%)

HURT: 2

or RV370:
total instructions in shared programs: 83946 -> 83944 (<.01%)

total cycles in shared programs: 132829 -> 132827 (<.01%)
