EVALUATION Fixed 6306741: Fix memory leaks in GrowableArrays used by GC. Backport memory leak cleanups in GC because customers complain when gc leaks memory more than in other places. Fix verified (y/n): y Verified by: ran GCBasher for a while, not easy to verify otherwise Other testing: runThese -jck -client/-server (which uses parallel and serial gc) Webrev: http://jruntime.east/~coleenp/webrev/6306741_bp/ Reviewed by: keith, ramki, jrose, kbr Approved by: Darin R.

EVALUATION Fix memory leaks in GrowableArrays found in tiger sources that occur during GC. EG. need to call + _promo_failure_scan_stack->clear_and_deallocate(); delete _promo_failure_scan_stack; + FreeHeap(_promo_failure_scan_stack); instead of just 'delete' because 'delete' doesn't return the C_HEAP memory used by the elements.
