Add support for Baker read barriers in UnsafeCASObject intrinsics.
Prior to doing the compare-and-swap operation, ensure the
expected reference stored in the holding object's field is
in the to-space by loading it, emitting a read barrier and
updating that field with a strong compare-and-set operation
with relaxed memory synchronization ordering (if needed).
Test: ART host and target tests and Nexus 5X boot test with Baker read barriers.
