The G1ReferentFieldReadBarrier is added when a read access is performed to the referent
field of a Reference object (through a LoadFieldNode or an
UnsafeLoadNode). The return value of the read is passed to the snippet implementing the
read barrier and consequently is added to the SATB queue if the concurrent marker is enabled.
