Adding postprocessing to remove "commutative cuts" expansions in pattern-matching when it turns after typing phase that no dependencies exists.
Adding postprocessing to remove "commutative cuts" expansions in
pattern-matching when it turns after typing phase that no dependencies exists.

it works both way (to generalize and to ungeneralize). This avoids
using replace_tomatch for ungeneralization which does not support
modifying the "deps".
