This is "concepts lite".

I think this was Doug Gregor's work, but I don't know how much of
ConceptGCC is present on the branch.

This is described at https://gcc.gnu.org/git.html as:

"This branch contains the beginnings of a re-implementation of Concepts, a
likely future feature of C++, using some of the code from the prototype
implementation on conceptgcc-branch. It is not currently maintained."

I don't know who did this work, check the git history.
