IR framework should not whitelist -XX:-UseTLAB

The IR framework currently whitelists UseTLAB and as a result, IR verification is enabled even if TLAB allocations are disabled which can lead to failures (because the IR differs).

Since JDK-8310187, test/hotspot/jtreg/compiler/gcbarriers/TestZGCBarrierElision.java fails in compiler stress testing (stress-comp-no-tlab) with -XX:-UseTLAB:
