Unreviewed, rolling back in r190450
​https://bugs.webkit.org/show_bug.cgi?id=149727

The cause of the leak was VM shutdown, which happens in workers.

The fix is for CodeBlockSet to participate in lastChanceToFinalize,
since it's responsible for running CodeBlock destructors.

I ran the leaks tests locally and did not see any CodeBlock-related leaks.

Restored changesets:

"CodeBlock should be a GC object"
