Introduce a Marking Register in ARM code generation.
When generating code for ARM, maintain the status of
Thread::Current()->GetIsGcMarking() in register R8,
dubbed MR (Marking Register), and check the value of that
register (instead of loading and checking a read barrier
marking entrypoint) in read barriers.
Test: m test-art-target
Test: m test-art-target with tree built with ART_USE_READ_BARRIER=false
Test: m test-art-host-gtest
Test: ARM device boot test
