Rhys Perry e36e295393 spirv: run nir_copy_prop before nir_rematerialize_derefs_in_use_blocks_impl 
spirv_to_nir sometimes wraps derefs in vec2 or mov instructions as part of
its texture handling. These get in the way of
nir_rematerialize_derefs_in_use_blocks_impl. Running copy propagation
should get rid of the extra move instructions and get us back to intact
deref chains for everything except variable pointer use-cases.
