@rsmith @aaron.ballman - might be especially interesting to know your thoughts 
on the C++ chapter-based testing and what the intent there is as clang changes 
default versions/new versions are added. (& also whether there's an approach 
(like moving the default language into the driver) that'd be worthwhile to 
lower the maintenance cost of these sort of migrations without compromising on 
test coverage/ending up with all the test coverage testing previous versions of 
the language and not what everyone's using in the wild)



================
Comment at: clang/test/CXX/class.access/class.friend/p1.cpp:4
 // RUN: %clang_cc1 -fsyntax-only -verify -std=c++14 %s
-// RUN: %clang_cc1 -fsyntax-only -verify %s
 
----------------
Might be worth knowing the version history of tests like this? (in here and 
other test files) - perhaps the intent is for this test to check the code is 
valid in all language versions & so should grow more explicit version lines as 
the language evolves?
