TODO:
- Add full unicode canonicalize rules for character ranges (not
really useful but needed for exact "ignorecase" compatibility).
- Add a lock step execution mode (=linear time execution guaranteed)
when the regular expression is "simple" i.e. no backreference nor
complicated lookahead. The opcodes are designed for this execution
