Done (commit daf38d3).

@offamitkumar @feilongjiang @snazarkin please note that the ADL instructions `g1XChgP` and `g1XChgN` have been renamed to `g1GetAndSetP` and `g1GetAndSetN`, and the same naming is expected across all platforms by the test `compiler/gcbarriers/TestG1BarrierGeneration.java` included in this changeset.
