I briefly looked at the implementation and I suspect that you folks might be reinventing [`ConstructionContext`](https://clang.llvm.org/doxygen/classclang_1_1ConstructionContext.html) which is typically¹ already available in the CFG. (Under an off-by-default CFG build option.) (I'm in favor of turning it on by default.) (Together with a few other options that improve precision, eg. copy elision and RVO support.)

¹ Not all of the 30+ possible construction contexts are currently implemented. But your visitor doesn't seem to implement them either.
