This adds a lot of factorisation and simplifications to the Z3 solver
backend. On a basic switch creation example, the size of the generated
.smt2 is down from 34000 lines to 6000, and the speedup around 40%.
Also fixes a correction bug that seemed to be present on master.
note: the patches in this PR should probably be squashed.
