----------------
I'm not really keen on this sort of change because it loses test coverage for other language standard versions. We usually try to write our tests to be standard version agnostic and only specify a specific language mode only when absolutely necessary, which doesn't seem to be the case for a lot of the tests in this patch (like this one).

// RUN: %clang_cc1 -fsyntax-only -fexceptions -fcxx-exceptions -verify -std=c++11 %s

+// RUN: %clang_cc1 -fsyntax-only -fexceptions -fcxx-exceptions -verify -std=c++14 %s
int *use_new(int N) {
----------------
This is another example where we lose all testing in the future when we go to change the default language standard version. It's fine to have a C++14-specific test, but we should still have a test which has no mode specified.
