C++17 deprecated std::iterator and removed it as a base class for all
iterator adaptors. We implement that change, but we still provide a way
to inherit from std::iterator in the few cases where doing otherwise
would be an ABI break.

Supersedes D101729 <https://reviews.llvm.org/D101729> and the std::iterator base parts of D103101 <https://reviews.llvm.org/D103101> and D102657 <https://reviews.llvm.org/D102657>.
