Make -std=c++17 an alias of -std=c++1z
As suggested on PR33912.
Trying to keep this small to make it easy to merge to the 5.0 branch. We
can do a follow-up with more thorough renaming (diagnostic text,
options, ids, etc.) later.
(For C++14 this was done in r215982, and I think a smaller patch for the
3.5 branch:
