fix: use a def-eq aware mapping at toLinearExpr
...
The new test exposes the problem fixed by this commit.
In the termination proof we have two `sizeOf xs` terms that are not
syntactically identical (only definitional equal) because the
instances are different.

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.

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`.
