GC should reclaim garbage even when new objects are not being allocated rapidly

Patch by Nathan Lawrence <​[email protected]> on 2010-08-03
Reviewed by Oliver Hunt.

Added a callback in JavaScriptCore that gets triggered after an
allocation causes the heap to reset. This is useful for adding a
timer that will trigger garbage collection after the "last" allocation.

Also needed was to add lock and unlock methods to JSLock that needed
only a JSGlobalData object versus an ExecState object.
