Subject: Replace `gUseReadBarrier` with compiler option in compiler.

Leave a few `gUseReadBarrier` uses in JNI macro assemblers.
We shall deaal with these later.

Test: m test-art-host-gtest
Test: testrunner.py --host --optimizing
Test: run-gtests.sh
Test: testrunner.py --target --optimizing
Bug: 289805127
