[Mesa-dev] [PATCH] ac/nir_to_llvm: fix clamp shadow reference for more hardware

[Timothy Arceri]

Fixes the following piglit test on my VEGA and matches the behaviour in the
tgsi backend.

tests/spec/glsl-1.10/execution/samplers/glsl-fs-shadow2D-clamp-z.shader_test

Fixes: 625dcbbc4566 ("amd/common: pass address components individually to ac_build_image_intrinsic")
