Revert "[silgen] Ensure that the outer cleanup is emitted along failure paths when initializing sub-tuple patterns"

This reverts commit be922b9.

By adding some extra scopes here we are triggering some broken behavior in a
bunch of projects. I am going to see if I can do another fix for this. That
being said in the short term, we are reverting to unblock those projects.
