amd/llvm: Fix divergent descriptor regressions with radeonsi.
piglit/bin/arb_bindless_texture-limit -auto -fbo: Needed to deal with non-NULL dynamic_index without deref in tex instructions. piglit/bin/shader_runner tests/spec/arb_bindless_texture/execution/images/multiple-resident-images-reading.shader_test -auto: Need to deal with non-deref images in enter_waterfall_imae.
