Instantiation dependence were not being handled correctly for OpqaueValueExpr AST nodes. As a result, if an undeclared identifier was used in a CXXNewExpr that is assigned to a ObjC property, there would be no error during parsing, and there would be a crash during code gen. This patch makes sure that an error will be issued during parsing in this case. Before the fix, if CXXNewExpr has a typo, its InstantiationDependent will be set to true, but if it is wrapped in a OpaqueValueExpr, the OpaqueValueExpr will not be instantiation dependent, causing the TypoExpr not be to resolved. The fix propagates InstantiationDependent to OpaqueValueExpr from its SourceExpr. It also propagates the other instantiation bits. rdar://24975562 Differential Revision: http://reviews.llvm.org/D18461 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@264444 91177308-0d34-0410-b5e6-96231b3b80d8
