A bunch-o changes to fix <rdar://problem/5716046> incomplete implementation of ObjC class warning is incomplete
...
As part of this fix, I made a low-level change to the text diagnostics machinery (to basically avoid printing duplicate source lines/carets when you have multiple diagnostics that refer to the same exact place). For now, this only happens with we don't have a source range (could be extended to support source ranges as well).
