o3: Fix issue with LLSC ordering and speculation
This patch unlocks the cpu-local monitor when the CPU sees a snoop to a locked address. Previously we relied on the cache to handle the locking for us, however some users on the gem5 mailing list reported a case where the cpu speculatively executes a ll operation after a pending sc operation in the pipeline and that makes the cache monitor valid. This should handle that case by invaliding the local monitor.
