This change caused all spec@arb_gpu_shader5@texturegatheroffsets tests
to fail an assertion with radeonsi and llvmpipe (needs
MESA_EXTENSION_OVERRIDE="GL_ARB_gpu_shader5" to run these tests). For
example textureGather fs offsets r 0 float 2D repeat:
../../../../src/gallium/auxiliary/gallivm/lp_bld_tgsi.c:442:lp_build_emit_fetch_texoffset:
Assertion `off->Index <= bld_base->info->file_max[off->File]' failed.
Thread 1 "textureGather" received signal SIGTRAP, Trace/breakpoint trap.
