Patch against concepts-cxx2a (git format-patch format)

Adds a test for PR78752, which had been semi-fixed. The attached patch rebuilds
constraints involving abbreviated functions with function argument packs and
updates the corresponding template parameter list. We weren't doing that
before, so we were checking constraints with the wrong arguments.
