Nuno Lopes eb8c53c164 simplify factory of dependent_expr_state_tactic 
And as a side-effect, remove heap allocations for factories
 2022-12-05 14:07:57 +00:00
Nikolaj Bjorner dd1ca8f6bd move qhead to attribute on the state instead of the simplifier, 
- add sat.smt option to enable the new incremental core (it is not ready for mainstream consumption as cloning and other features are not implemented and it hasn't been tested in any detail yet).
- move "name" into attribute on simplifier so it can be reused for diagnostics by the seq-simplifier.

Nikolaj Bjorner e57674490f adding simplifiers layer 
simplifiers layer is a common substrate for global non-incremental and incremental processing.
The first two layers are new, but others are to be ported form tactics.

- bv::slice - rewrites equations to cut-dice-slice bit-vector extractions until they align. It creates opportunities for rewriting portions of bit-vectors to common sub-expressions, including values.
- euf::completion - generalizes the KB simplifcation from asserted formulas to use the E-graph to establish a global and order-independent canonization.

The interface dependent_expr_simplifier is amenable to forming tactics. Plugins for asserted-formulas is also possible but not yet realized.

Nikolaj Bjorner fc77345bec breaking change. Enforce append semantics everywhere for parameter updates #5744 
Replace semantics doesn't work with assumptions made elsewhere in code.
The remedy is to apply append (override) semantics for parameter changes.
