From: Ian Romanick <ian.d.roman...@intel.com>
Previously, shader-db runs on Gen5 through Haswell would spew tons of
messages like:
VS instruction not yet implemented by NIR->vec4
I checked several instance of this, and all of them were
nir_instr_type_deref instructions in vertex shaders that had texture
accesses (e.g., UnrealEngine4/EffectsCaveDemo/239.shader_test).
Solution copied directly from fs_visitor::nir_emit_instr.

Fixes: 5a02ffb733e nir: Rework lower_locals_to_regs to use deref instructions
