Nikolaj Bjorner 4a870966ad add code to enable unit propagation of bounds 
set UNIT_PROPAGATE_BOUNDS 1 to use the unit propagation version. It applies unit propagation eagerly (does not depend on checking LIA consistency before final check) and avoid creating new literals in most cases

Nikolaj Bjorner 61319ffd85 cache is_shared information in the enode 
observed perf overhead for QF_NIA is that assume_eqs in theory_lra incurs significant overhead when calling is_relevant_and_shared. The call to context::is_shared and the loop checking for beta redexes is a main bottleneck. The bottleneck is avoided by caching the result if is_shared inside the enode. It is invalidated for every merge/unmerge.

QEL: Fast Approximated Quantifier Elimination (#6820) 
* qe_lite: cleanup and comment

no change to code

* mbp_arrays: refactor out partial equality (peq)

Partial array equality, PEQ, is used as an intermediate
expression during MBP for arrays. We need to factor it out
so that it can be shared between MBP-QEL and existing MBP.

Partial array equality (peq) is used in MBP for arrays.
Factoring this out to be used by multiple MBP implementations.

* rewriter: new rewrite rules

These rules are specializes for terms that are created in QEL.
QEL commit is comming later

* datatype_rw: new rewrite rule for ADTs

The rule handles this special case:

    (cons (head x) (tail x)) --> x

* array_rewriter rules for rewriting PEQs

Special rules to simplify PEQs

* th_rewriter: wire PEQ simplifications

* spacer_iuc: avoid terms with default in IUC

Spacer prfers to not have a term representing default value of an array.
This guides IUC from picking such terms in interpolation

* mbp_term_graph: replace root with repr

* mbp_term_graph: formatting

* mbp_term_graph: class_props, getters, setters

Class properties allow to keep information for an equivalence class.

Getters and setters for terms allow accessing information

* mbp_term_graph: auxiliary methods for qel

QEL commit is comming later in the history

* mbp_term_graph: bug fix

* mbp_term_graph: pick, refine repr, compute cgrnd

* mbp_term_graph: internalize deq

* mbp_term_graph: constructor

* mbp_term_graph: optionally internalize equalities

Reperesent equalities explicitly by nodes in the term_graph

* qel

* formatting

* comments on term_lt

* get terms and other api for mbp_qel

* plugins for mbp_qel

* mbp_qel_util: utilities for mbp_qel

* qe_mbp: QEL-based mbp

* qel: expose QEL API

* spacer: replace qe_lite in qe_project_spacer by qel

This changes the default projection engine that spacer uses.

* cmd_context: debug commands for qel and mbp_qel

New commands are

  mbp-qel -- MBP with term graphs
  qel     -- QEL with term graphs
  qe-lite -- older qelite

* qe_mbp: model-based rewriters for arrays

* qe_mbp: QEL-based projection functions

* qsat: wire in QEL-based mbp

* qsat: debug code

* qsat: maybe a bug fix

Changed the code to follow the paper by adding all predicates above a given
level, not just predicates of immediately preceding level.

* chore: use new api to create solver in qsat

* mbp_term_graph use all_of idiom

* feat: solver for integer multiplication

* array_peq: formatting, no change to code

* mbp_qel_util: block comment + format

* mbt_term_graph: clang-format

* bug fix. Move dt rewrite to qe_mbp

* array_peq: add header

* run clang format on mbp plugins

* clang format on mul solver

* format do-while

* format

* format do-while

* update release notes

Nikolaj Bjorner adad468cd7 allow copy within a user scope #6827 
this will allow copying the solver state within a scope.
The new solver state has its state at level 0. It is not possible to pop scopes from the new solver (you can still pop scopes from the original solver). The reason for this semantics is the relative difficulty of implementing (getting it right) of a state copy that preserves scopes.

Nikolaj Bjorner 8a913981f6 fix #6813 - proofs terms are fragile with respect to simplificiation of not(not(e)). It would be better if proof terms didn't have to track this level of detail, but the legacy proof format assumes strictly checkable proofs. A patch is to fixup terms within the mk_transitivity constructor

Nikolaj Bjorner 939bf1c725 wip - alpha support for polymorphism 
An initial update to support polymorphism from SMTLIB3 and the API (so far C, Python).

The WIP SMTLIB3 format is assumed to be supporting the following declaration

```
(declare-type-var A)
```
Whenever A is used in a type signature of a function/constant or bound quantified variable, it is taken to mean that all instantiations of A are included in the signature and assertions.
For example, if the function f is declared with signature A -> A, then there is a version of f for all instances of A.
The semantics of polymorphism appears to follow previous proposals: the instances are effectively different functions.
This may clash with some other notions, such as the type signature forall 'a . 'a -> 'a would be inhabited by a unique function (the identity), while this is not enforced in this version (and hopefully never because it is more busy work).

The C API has the function 'Z3_mk_type_variable' to create a type variable and applying functions modulo polymorphic type signatures is possible.
The kind Z3_TYPE_VAR is added to sort discriminators.

This version is considered as early alpha. It passes a first rudimentary unit test involving quantified axioms, declare-fun, define-fun, and define-fun-rec.
