Meghana Gupta f30b5841c4 Tolerate undef closure captures in ClosureLifetimeFixup ...

We may see undef closure captures in ClosureLifetimeFixup since
it is a mandatory pass that runs on invalid code as well.

This could sometimes hang the compiler while running `insertDeallocOfCapturedArguments`
in release builds.

This change adds a bailout when we see an undef closure capture to avoid running into this issue.
