r180741 - [analyzer] Change PathPieces to be a wrapper around an ilist of (through indirection) PathDiagnosticPieces.

std::list does support ripping out and inserting nodes in place (using the iterator versions of insert() and erase()), and using an ilist for a non-intrusive list seems weird.
I'm fairly sure flattening can still cause problems for when diagnostics are output twice, because PathDiagnosticPiece objects that contain path segments themselves really do need to be copied to make them independent. I don't think we really have a way to "share" the path pieces unless we have some kind of deepCloneNoLeaves() method.
