ARM64: Use link-time generated thunks for Baker CC read barrier.
Remaining work for follow-up CLs:
- array loads,
- volatile field loads,
- use implicit null check in field thunk.
Test: Added tests to relative_patcher_arm64
Test: New run-test 160-read-barrier-stress
Test: m test-art-target-gtest on Nexus 6P.
Test: testrunner.py --target on Nexus 6P.
