Subject: ObjCCategoryImplDecl and ObjCImplementation do not derive directly from DeclContext... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=bfb498d0996ef049efe9476f2802976fd145cd60;p=clang

ObjCCategoryImplDecl and ObjCImplementation do not derive directly from DeclContext but from a new abstract ObjCImplDecl.
Reflect this change on the "DeclContext hierarchy".
