[index] Fix issue with protocol name locations in conformance list of an ObjC class when they come from a typedef.
The ObjC class protocol list assumes there is an associated location for each protocol but no location is provided
when the protocol list comes from a typedef, and we end up with a buffer overflow when trying to get locations for the protocol names.
Fixes crash of rdar://28980278.
