Summary: We want to detect that variables and C++ temporaries go out of scope even when their destructor happens to be modelled. We lost a test to that because `std::function::~function` was poorly modeled as deleting the lambda itself which would now cause a double invalidation. This has to be modelled better now as something that invalidates something *inside* the lambda, and also model `operator()` as something that accesses that something, to recover that test. It's not a vital test though, so Do It Later©. Reviewed By: ngorogiannis Differential Revision: D16121091 fbshipit-source-id: 6b777ca18
