Note: the atomic host-mem-barrier tests assume that the atomic
buffer could be shared which is not how the r600 operates.

This change was tested on palm and cayman, with the exception
of the "atomic counter" tests, it fixes all the other cases:
spec/arb_shader_image_load_store/host-mem-barrier/.*: fail pass
