Summary: We were treating subprograms and inlined subroutines differently when building the index. The difference was in which indexes were individual tags inserted (subprograms went to all indexes, where as inlined subroutines only into the basename and full name indexes). This seems like an error, because an inlined subroutine can still represent an C++ or an ObjC method. I don't see anything in the subprogram branch which should not apply to an inlined subroutine, so I propose to just treat them identically. This makes searching for an inlined method behave the same way as for the apple index. I write an assembly-based test because I did not want to depend on particular clang inlining behavior (and because I wanted to see how hard would it be).
