ART: Add stack-dump mode for contention logging
Add a second threshold to contention logging. If this threshold
is reached, log the owner and the contender thread to the logcat.
Requires a bit of refactor in the contention logging code to hold
the locks correctly (different requirements for owner and contender).
Add -Xstackdumplockprofthreshold:ms to control the threshold value.
As with general contention logging, default to 0 = off. Use ThreadStress
with --locks-only to get test coverage.
