RFR: 8329351: add runtime/Monitor/TestRecursiveLocking.java for recursive Java monitor stress testing

[Daniel D. Daugherty]

The first stress test to be added is:

runtime/Monitor/TestRecursiveLocking.java

It has been tested with a couple of 12 hour runs on my MBP13:
  - 3 build configs: release, fastdebug, slowdebug, 4 hours each, total 12 hours
  - 18 test configs, 800 seconds each, total 4 hours

The default configuration has been tested in Mach5 Tier2 and the
StressWrapper_TestRecursiveLocking_36M.java version has been
tested in Mach5 Tier3.
