Add fast path to arm64 READ_BARRIER macro
EAAC benchmark time from 978.7857143ms to 969.5714286ms on N9 based
on 42 samples. Reduces artReadBarrierSlow calls from 9M to 1M.
Not a huge improvement since we were already checking the lock word in
ReadBarrier::Barrier.
Test: N9 boots, test-art-host, EEAC runs. (All with CC enabled).
