llvm dev - Nov 2015 - TraverseObjCTypeParamDecl usage in RecursiveASTVisitor

Hello.

RecursiveASTVisitor changes from r241541 are calling 
TraverseObjCTypeParamDecl directly from Traverse ObjCCategoryDecl and 
Traverse ObjCInterfaceDecl instead of using TraverseDecl. Is there a 
specific reason for that?

I would expect that TraverseDecl is used as entry point for all 
Traverse...Decl methods. Calling Traverse...Decl directly skips 
additional checks from RecursiveASTVisitor::TraverseDecl and all sub 
classes that extend it.
