History
Nikolaj Bjorner 2e3dd32b90 Address PR review comments: cache, simplify_ite_rec, itos 
- Cache now indexes by (ele, r) pair using obj_pair_map
- Remove eval() function; operator()(ele, r) handles all cases
- Rewrite simplify_ite_rec with path vector of signed conditions
- Add range-based simplification: (lo <= x, false) + (x <= hi, false)
  eliminates ite(x = v, t, e) when v is outside [lo, hi]
- Add is_itos case in derive_to_re: guards on n >= 0, digit range,
  and first character match
- Port is_reverse normalization (previous commit)
