[Mesa-dev] [PATCH v2 1/3] i965: Sweep NIR after linking phase to free held memory

After optimization passes and many trasfromations most of memory
NIR holds is a garbage which was being freed only after shader deletion.
Freeing it at the end of linking will save memory which would be useful
in case there are a lot of complex shaders being compiled.
The common case for this issue is 32bit game running under Wine.
The cost of the optimization is around ~3-5% of compilation speed
with complex shaders.
V2: by Jason Ekstrand
- Move nir_sweep up, right after the last change of NIR
