add opt_NoQuickReturn_IntegerTheory check in theory_str::new_eq_check()
...
This allows us to assert an "inconsistent length" axiom from the integer theory
while continuing in new_eq_handler(). Currently active when
opt_NoQuickReturn_IntegerTheory is 'true' but this may be necessary
here and in other places, in general, to fix integer theory integration.

add option to bypass quick returns in integer theory integration in theory_str
...
this might not actually be that useful, if the problem is, as I suspect it to be,
that values we get from the integer theory need not correspond with
assertions in the core (that can get popped off the stack, etc.)

add general-case regex unroll model generation
...
WIP as there is currently a SAT-as-UNSAT bug I'm trying to fix
This also changes the semantics of lower_bound and upper_bound,
no longer wrapping the expr that is passed in with mk_strlen().
This actually makes these methods useful for checking bounds
of things other than strings.
