A terrifying amount of code, including large chunks of open source code, still do this so it's important to be able to suppress it when necessary. Doug, is this a reasonable compromise? I'd lean toward making it a normal extension, but I don't feel strongly as long as we can turn the warnings off. llvm-svn: 107865

* Changes how the TypeLoc traverser invokes the Type traverser: before,Zhanyong Wan2010-07-071-64/+60
| | | | | | | | | | | | | | | | | | | VisitFooTypeLoc() calls VisitFooType(); now, TraverseFooTypeLoc() calls WalkUpFromFooType(). This allows clients that override WalkUpFromFooType() to continue to work. It also preserves the property that Visit*() in the base visitor class is a no-op (s.t. a subclass doesn't have to call Base::Visit*() when overriding Visit*()). Also fixes some typos in comments. Also added a missing getDerived() inside TraverseQualifiedTypeLoc(). The call is needed in case a subclass overrides TraverseTypeLoc(). Reviewed by nlewycky and csilvers. llvm-svn: 107816
