a lambda. Bug #1 is that CGF's CurFuncDecl was "stuck" at lambda invocation functions. Fix that by generally improving getNonClosureContext to look through lambdas and captured statements but only report code contexts, which is generally what's wanted. Audit uses of CurFuncDecl and getNonClosureAncestor for correctness. Bug #2 is that lambdas weren't specially mapping 'self' when inside an ObjC method. Fix that by removing the requirement for that and using the normal EmitDeclRefLValue path in LoadObjCSelf. rdar://13800041 llvm-svn: 181000
