This is the resolution for #6633.
This PR moves bidirectional-common to [range.utility.helpers] also with slide-caches-nothing which renames it to random-access-sized:

template<class R>
  concept bidirectional-common = // exposition only
    bidirectional_range<R> && common_range<R>;
template<class R>
  concept random-access-sized = // exposition only
    random_access_range<R> && sized_range<R>;

Then replace them where they are used in [ranges].
I believe this is editorial, and it simplifies the spelling of a number of concepts without reducing readability, which is an improvement in my opinion.

And I think this also helps with the concept spelling for newly-introduced range adaptors.

Comments are welcome.
