65a8c162f5 add E(T) functionality for bv and ac functions 
Add an option to register EUF modulo theories,
The current theory with a unit test is BV.
The arithmetic theory plugs into an AC completion. It is partially finished, pending setting up testing and implementing handling of shared terms.

f8c9ed1d90 Revisit ule_constraint simplifications and add unit test for this 
If we can be certain of simplification results,
it is easier to recognize patterns for fixed bits and similar.

c95ff56d2d slicing: change how values are tracked 
Do not eagerly merge equivalence classes with the same constant value.

Reason:
- when we split a value slice, the subslice might already exist in the
  egraph and already have subslices itself, which breaks assumptions in
  split/split_core.
- introduces unnecessary splits

Now:
- wrap constants into fresh function symbol before creating the enode
- check value compatibility in on_merge callback instead
- track pointer to value_node for each enode, and update it in on_merge
