[analyzer; alternate edges] Fix the edge locations in presence of macros.

We drew the diagnostic edges to wrong statements in cases the note was on a macro.
The fix is simple, but seems to work just fine for a whole bunch of test cases (plist-macros.cpp).

Also, removes an unnecessary edge in edges-new.mm, when function signature starts with a macro.
