intel/compiler: emit actual barriers for working-group level barriers

Until now we have assumed that we could skip emitting these barriers
in the general case based on empirical testing and a few assumptions
detailed in a comment in the driver code, however, recent CTS tests
have showed that we actually need them to produce correct behavior.
