[JSC] JITWorklist::visitWeakReferences() should bail if the VM has no active
plans
https://bugs.webkit.org/show_bug.cgi?id=293711
rdar://150606516
Reviewed by Keith Miller and Mark Lam.
When the VM being collected has no JITPlans, there's no point in
JITWorklist::visitWeakReferences() searching for a plan, so bail
earlier like the other methods do. This avoids a racy check
of the safepoint since the JIT threads might not be suspended.
Add an assert that verifies the invariant that avoids this race.
