I think this should fix the problem.  I tested on Broadwell with:

MESA_EXTENSION_OVERRIDE=GL_ARB_compute_shader valgrind
bin/arb_shader_image_load_store-semantics -fbo -auto --quick

and saw valgrind errors before these patches, and none after.  I haven't tried
running dEQP through valgrind, though.
