+        return a_deps.find(b) != a_deps.end() 
+            || b->getLocation() < a->getLocation(); // ensure deterministic 
ordering
+      });
----------------
Is the call to a_deps.find() here actually necessary?  It shouldn't be possible 
for an initializer to directly refer to a variable declared later.

"<" on SourceLocations isn't source order, in general; you need 
isBeforeInTranslationUnit.  (This should be documented somewhere, but I'm not 
finding the documentation, unfortunately.  Any suggestions for where it should 
be documented?)
