The memory pressure handler currently calls GCController::deleteAllCode(DeleteAllCodeIfNotCollecting), but it turns out we hit the case of a collection being in progress moderately often. We already do a bunch of blocky work here to get memory usage down, so let's change this to PreventCollectionAndDeleteAllCode to guarantee we can drop all JIT code.
