8038930: G1CodeRootSet::test fails with assert(_num_chunks_handed_out == 0) failed: No elements must have been handed out yet Summary: The test incorrectly assumed that it had been started with no other previous compilation activity. Fix this by allowing multiple code root free chunk lists, and use one separate from the global one to perform the test. Reviewed-by: brutisso
