Summary: Add a `cleanupendpad` instruction, used to mark exceptional exits out of cleanups (for languages/targets that can abort a cleanup with another exception). The `cleanupendpad` instruction is similar to the `catchendpad` instruction in that it is an EH pad which is the target of unwind edges in the handler and which itself has an unwind edge to the next EH action. The `cleanupendpad` instruction, similar to `cleanupret` has a `cleanuppad` argument indicating which cleanup it exits. The unwind successors of a `cleanuppad`'s `cleanupendpad`s must agree with each other and with its `cleanupret`s. Update WinEHPrepare (and docs/tests) to accomodate `cleanupendpad`.
