For ObjCXX, we can create a CastExpr with Kind being CK_UserDefinedConversion and SubExpr being BlockExpr. Specifically one can return BlockExpr from BuildCXXMemberCallExpr and the result can be used to build a CastExpr. Fix the assumption in CastExpr::getSubExprAsWritten that SubExpr can only be CXXMemberCallExpr. rdar://problem/24364077 llvm-svn: 259591
