Unlike the rest of our SB objects, SBEvent and SBCommandReturnObject have the ability to hold non-owning pointers to their non-SB counterparts. This makes it hard to ensure the SB objects do not become dangling once their backing object goes away. While we could make these two objects behave like others, that would require plubming even more shared pointers through our internal code (Event objects are mostly prepared for it, CommandReturnObject are not). Doing so seems unnecessarily disruptive, given that (unlike for some of the other objects) I don't see any good reason why would someone want to hold onto these objects after the function terminates. For that reason, this patch implements a different approach -- the SB objects will still hold non-owning pointers, but they will be reset to the empty/default state as soon as the function terminates. This python code will not crash if the user decides to store these objects -- but the objects themselves will be useless/empty. Differential Revision: https://reviews.llvm.org/D116162
