Fix cases where we miss instrumentation changes
Moved allocation stack push to after we record the allocation since
it can cause thread suspension.
Added handling in entrypoint utils for thread suspension cases.
Keep the AllocRecordObjectMap around since we do not want to delete
it if there are any threads waiting on new_record_condition_. The
condition guards adding stack traces while the GC is running. If we
delete the map and there are still waiters that did not resume, it
caused a CHECK failure. This could happen in cases where one thread
disables allocation tracking while other threads are about to
resume from the condition.
