Extended Description

My understanding is that it is now extremely unlikely that C++17 will end up becoming C++18, so perhaps the time has come to add -std=c++17. GCC has had it for a while, and it would be convenient if Clang also recognized it.

Thanks!

Richard, should we do this for clang 5?

[zygoloid]

Seems like a good idea to me. The committee intends to call the new standard C++17 even if it ends up being published next year.
