This is a cleanup of C1 related code: - Removed tmp1 and tmp2 from the ShenandoahWriteBarrier op (currently not needed) - Removed unused includes - Several whitespace fixes to make code as close as possible to upstream - Removed shenandoah_write_barrier_slow_id stub. we now use the shared WB stub http://cr.openjdk.java.net/~rkennke/c1-cleanup/webrev.00/ Ok?
