This PR makes `PProdN.reduceProjs` also look for projection functions. Previously, all redexes were created by the functions in `PProdN`, which used primitive projections. But with `mkAdmProj` the projection functions creep in via the types of the `admissible_pprod_fst` theorem. So let's just reduce both of them. Fixes #9462. |
