Fix ART ARM64 CFI gtests with GCs other than CC with Baker read barriers.
Since the introduction of a Marking Register in the ARM64 back
end, gtests jni_cfi_test and optimizing_cfi_test produce
different outputs for the Concurrent Copying (CC) collector
with Baker read barriers on the one hand, and for other GCs on
the other hand.
Test: m test-art-host-gtest with tree built with ART_USE_READ_BARRIER=false
