Commit Message

Lower limits on `VF2PostLayout` in exact mode (#15068) (#15075)

We currently run `VF2PostLayout(strict=True)` after the optimisation
loop at optimisation level 3.  We use the same values for `call_limit`
and `max_trials` as we do for the averaging methods, but the averaging
methods are pure Rust with no semantic matching, whereas the exact-match
have Python-space semantic matching, so are far slower.

We can look at raising the limits back to much higher values when these
paths are in Rust and use the branch-and-bound scoring.

(cherry picked from commit 7052dfe47)
