Log Message:
-----------
CodeBlock should reset its StubInfo when jettisoned
https://bugs.webkit.org/show_bug.cgi?id=288554
rdar://144072285
Reviewed by Yusuke Suzuki.
CodeBlock's StubInfo can keep watchpoints alive which do not ref data they
hold, meaning
that when the CodeBlock is jettisoned, we may have dangling pointers to data
that was
freed during a GC.
