33b1d2fd98 fix: preserve arrow binder names and info at simp
We use the idiom `revert; simp; ...; intro` in a few places. Some of
the reverted hypotheses manifest themselves as arrows in the target.
Before this commit, `simp` would lose the binder names and info when
simplifying an arrow, and we would get inaccessible names when
reintroducing them.

7fc12014da fix: make sure splitTarget? skips match expressions that produce type errors at splitMatch
We can now generate the equation theorem for
```
attribute [simp] Array.heapSort.loop
```

e574c5373f feat: improve delta? method
Use zeta reduction to create new opportunities of beta-reduction.

This issue fixes on the problems that were affecting the generation of
equation theorems for `Array.heapSort.loop` (see issue: #998).
After this fix, the equation theorem generation fails at `splitMatch`.

It was just making it stop simplification at the current branch.

issue #906.
