I believe the C++17 RFC was already on LLVM-dev last I saw?

That said, I commented because we typically try to update the 'minimum 
versions' in lockstep best we can.  Bumping these versions is particularly 
arduous, so I'd be against trying to do it piece-meal like this, particularly 
as we're updating the NEWEST requirement (that is, VS2017 is newer than Clang 
3.5/GCC5.1!).

Also note that we have a 'policy' for bumping versions: 
https://llvm.org/docs/DeveloperPolicy.html#toolchain

(From the looks of it, I think we ARE following the policy, but others should 
take a look).
