i965/vec4: Use nir_move_vec_src_uses_to_dest
The idea here is not that it gives register coalescing a little bit of a
helping hand. It doesn't actually fix the coalescing problems, but it
seems to help a good bit.
Shader-db results for vec4 programs on Haswell:
total instructions in shared programs: 1746280 -> 1683959 (-3.57%)
instructions in affected programs: 1259166 -> 1196845 (-4.95%)
helped: 11363
HURT: 148
v2 (Jason Ekstrand):
- Run nir_move_vec_src_uses_to_dest after going out of SSA
- New shader-db numbers
