Re-enable run-test 484-checker-register-hints with read barriers.

The code generated by the x86 back end with all read barrier
configurations now satisfies all Checker assertions.

Test: ART_USE_READ_BARRIER=true make test-art-host-run-test-484-checker-register-hints
Test: ART_USE_READ_BARRIER=true ART_HEAP_POISONING=true make test-art-host-run-test-484-checker-register-hints
Test: ART_USE_READ_BARRIER=true ART_READ_BARRIER_TYPE=TABLELOOKUP make test-art-host-run-test-484-checker-register-hints
Test: ART_USE_READ_BARRIER=true ART_READ_BARRIER_TYPE=TABLELOOKUP ART_HEAP_POISONING=true make test-art-host-run-test-484-checker-register-hints
