[JSC] Ensure all visitWeak is called from StructureStubInfo
https://bugs.webkit.org/show_bug.cgi?id=294545
rdar://problem/153505034
Reviewed by Keith Miller.
Further safety related changes. Ensure that all children calls visitWeak
from StructureStubInfo to ensure everything is cleaned up before
StructureStubInfo and its stubRoutine gets destroyed eagerly.
