Support indexed operators re.loop and re.^ (#4167)
Towards support for the strings standard.
This modifies our interface so that we accept the SMT-LIB standard versions of re.loop and re.^. This means re.loop no longer accepts 3 arguments but 1 (with 2 indices).
This means we no longer accept re.loop with only a lower bound and no upper bound on the number of repetitions.
Also fixes #4161.
