We obviously can't analyze functions defined in a different translation unit, and I'm not sure we need to analyze even those defined in the same TU (since it may be imprecise and quite expensive), but maybe we should use some heuristic here (the most agressive would be to flag all initializers containing function calls, but that might be rather noisy).
The guidelines actually recommend flagging calls non-constexpr functions, but this would give too many positives. I've added a note.
