Don't assume that a new cleanup was added to InnermostEHScope.
After fa87fa97fb79, this was no longer guaranteed to be the cleanup
just added by this code, if IsEHCleanup got disabled. Instead, use
stable_begin(), which _is_ guaranteed to be the cleanup just added.
This caused a crash when a object that is callee destroyed (e.g. with the MS ABI) was passed in a call from a noexcept function.
Added a test to verify.
Fixes: fa87fa97fb79
