fix: do not split on if-then-else terms when generating equation theorems
...
Reason: avoid unnecessary case-analysis explosion
It is also unnecessary since we only refine the `below` and `F`
arguments over `match`-expressions.
This fixes the last case at issue #998

attribute [simp] BinaryHeap.heapifyDown

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`.
