True, but unlike runtime/os/TestTrimNative.java, this old test did nothing to

MonitoringSupport_lock is initialized only when UseG1GC is true, but
[JDK-8304074](https://bugs.openjdk.org/browse/JDK-8304074) uses it to implement
getTotalThreadAllocatedBytes, which is available for all garbage collectors.
While the current code sets UseG1GC regardless of which collector is s

Trivial patch.
The test just fires `jcmd System.trim_native_heap`, but without preparing any
special memory allocation conditions. Typically, we end up firing the command
when VM initialization is done, and therefore end up trimming a lot of memory.
But once in a blue moon concurrent allocation
Can I please get a review of this test-only change which removes usages of the
deprecated (no-op) `-Xdebug` from these tests? I missed these files when
addressing https://bugs.openjdk.org/browse/JDK-8227229.
tier testing with these changes has passed without issues.
