Instrument ARM generated code to check the Marking Register.

Generate run-time code in the Optimizing compiler checking that
the Marking Register's value matches `self.tls32_.is.gc_marking`
in debug mode (on target; and on host with JIT, or with AOT when
compiling the core image). If a check fails, abort.

Test: m test-art-target
Test: m test-art-target with tree built with ART_USE_READ_BARRIER=false
Test: ARM device/emulator boot test with libartd
