Nikolaj Bjorner d67919373e add bailout option for code review #5208 
@levnach
Could you review and maybe make this much more streamlined?
The patch is to simply bail out the iterator if it fails to find canonical monics.
If m_ff could produce the existing canonical monics up front this kind of bail-out could maybe avoided.
