Detailed Description

A cleanup whose destructor call is not emitted where the cleanup is registered.

Used by the lifetime-extended cleanup stack, whose entries are later promoted onto the EH scope stack, and by the deferred conditional cleanup stack, whose entries are emitted directly into a conditional scope's cleanup region.

A valid activeFlag means the cleanup is conditional. The flag tracks at run time whether the object has been constructed, and guards the destructor call.

Currently only DestroyObject cleanups use this. When other cleanup types are needed (e.g., CallLifetimeEnd), this struct can be extended with a std::variant of cleanup data types.
