Subject: -Add ObjCCategoryImplDecl::getCategoryClass() which returns the category interface... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=4292073a858f72769fa405b48390620c8932f8ae;p=clang

-Add ObjCCategoryImplDecl::getCategoryClass() which returns the category interface decl.
-Correct ObjCMethodDecl::getNextRedeclaration(); A method in a ObjCCategoryImplDecl should point to
a method in the associated ObjCCategoryDecl, not the ObjCInterfaceDecl.
