This PR improves support for `a^n` in `grind cutsat`. For example, if `cutsat` discovers that `a` and `b` are equal to numerals, it now propagates the equality. This PR is similar to #9996, but `a^b`. Example: ```lean example (n : Nat) : n = 2 → 2 ^ (n+1) = 8 := by grind ``` With #10022, it also improves the support for `BitVec n` when `n` is not numeral. Example: ```lean example {n m : Nat} (x : BitVec n) : 2 ≤ n → n ≤ m → m = 2 → x = 0 ∨ x = 1 ∨ x = 2 ∨ x = 3 := by grind ``` |
