  1. Contracts/DFCC: split conjunctions in loop invariants 

    Emitting one assertion (and assumption) per conjunct simplifies
debugging when proving a loop invariant fails. It also appears to
improve performance when using Bitwuzla, taking one example from more
than 30 minutes down to 8 seconds. On the same example, performance
using Z3 was not substantially different.
