While tightening up the test case I think I found an issue with the way inlined frames are handled. I need to take a closer look.

That's a totally fair point. The reason I've used unique_ptr here is to save space in CallEdge in the common case, where no call site information is loaded for the function. Call site info is lazily parsed, so we'd like to take a minimal memory hit for functions that aren't in a backtrace.

Also, note that using a pointer allows for a further PointerIntPair memory optimization mentioned below.
