r600: move stores to the end of shader when required

Browse source 
This change is inspired from 1e0e521a7d ("broadcom/compiler:
move stores to the end of shader") and makes the khr cull_distance
tests which were broken after dae57e184a functionals again.

Fixes: dae57e184a ("glsl,st/mesa: always lower IO for GLSL, unlower IO for drivers")
