[PATCH] D152655: [MC] Merge MC[Sub,Super]RegIterator with mc_[sub,super]_reg_iterator

[Sergei Barannikov via Phabricator via llvm-commits]

This is an NFC to make D152098 <https://reviews.llvm.org/D152098> simpler.

There is a bit of boilerplate in the form of overridden `operator++` because forward iterators
require `operator*` to return by reference ( C++ <= 17 AFAIK). `concat_range` relies on this.
`operator++` caches the value so that `operator*` can return a reference.
