Make lambda rewriter more robust (#3806)

The lambda rewriter was not robust to the case where the lambda of the
array representation contained a disequality, e.g. `not(x = 1))`. It
would process it as `ite(not(x = 1), true, false)` instead of `ite(x =
1, false, true)`, which meant that it wasn't able to turn it into an
array representation when checking const-ness. Additionally, the
rewriter had issues when the lambda was of the form `ite((= x c1), true,
(= y c2))` (after turning it into an array and then into a lambda)

Regression tests for arithmetic proofs. (#3701)

* Add more arith proof regression tests

These tests are designed to test interesting cases of arithmetic proofs,
such as mixing integers and reals and tightening bounds.

Right now, they have the --no-check-proofs flag set, which prevents them
from testing the proof machinery. However, once we check that machinery
into master, we'll remove that flag, thus enabling the full effect of
the tests.

* A few comments explaining things.

* Add another tightening test

* Add new test to CMake

* No --no-check-models. There are no models anyway.

* Delete smt-lib-version, per Yoni
