        Description

        1) Added assertion to catch evacuation after completion of heap traversal. This should help catch the bug demonstrated in sh-jdk11 w/o JDK-8237396.

        2) Retire TLAB/GCLAB after completion of heap traversal. Current code retires TLAB/GCLAB at the beginning final traversal, but STW traversal still uses GCLAB to evacuate remaining objects.

        3) Added comments regarding why need to retire TLAB/GCLAB, even we don't need heap to be parsable.
