fix: missing propagation and split filter in grind ( #7926 )
...
This PR fixes two issues that were preventing `grind` to solve
`getElem?_eq_some_iff`.
1. Missing propagation rule for `Exists p = False`
2. Missing conditions at `isCongrToPrevSplit` a filter for discarding
unnecessary case-splits.

feat: improve Bool normalization in grind ( #7862 )
...
This PR improves the normalization of `Bool` terms in `grind`. Recall
that `grind` currently does not case split on Boolean terms to reduce
the size of the search space.

fix: Bool disequality propagation in grind ( #7781 )
...
This PR adds a new propagation rule for `Bool` disequalities to `grind`.
It now propagates `x = true` (`x = false`) from the disequality `x =
false` (`x = true`). It ensures we don't have to perform case analysis
on `x` to learn this fact. See tests.
