So we had an issue with some of the slices proofs. They ran in addLocalFacts which learned all values's proofs. The problem is that some proofs are only valid after executing certain values. This happens when a value adds relations in the factsTable about exclusively the value's arguments. But due to the descend / simplify separation simplify would run with all the proofs of the whole block. This CL include a huge amount of retabulation of code, all the meaningfull part is the changes to the prove function. Now we run: 1. flowLimit 2. constantFoldArguments 3. addValueFact 4. simplifyValue inside the same value loop. So thanks to toposorting, facts are learned in a valid execution order. And thanks to interleaving simplify for value v can only see v's facts.
