[Eric Fiselier via Phabricator]

Quick Question: What's the difference between writing `_VSTD::` and `std::`? Nothing.

This lack of functional difference makes `_VSTD::` confusing, and makes it unclear when it should be used. The effect of `std::`, however, is perfectly clear to all readers of C++.
