it uses copy constructor instead of move when returning a scoped_anum in functions such as power and root.
This leads to freeing memory that gets passed as return value.
The copy constructor for scoped_numeral is also suspicious because it doesn't ensure memory ownership.
* sat_literal: make constants constexpr
* dlist: rename elem -> list
* tbv: use get_bit
* additional pdd and rational tests
* egraph: callback setters take functions by value
This allows to set callbacks without defining a separate variable for
the callback lambda.
(previous usage does one copy of the function, exactly as before)
* cmake: enable compiler error when non-void function does not return value
plugin setting allows adding equality saturation within the E-graph propagation without involving externalizing theory solver dispatch. It makes equality saturation independent of SAT integration.
Add a special relation operator to support ad-hoc AC symbols.

- convert reduce-args to a simplifier. Currently exposed as reduce-args2 tactic until the old tactic code gets removed.
- bug fixes in model_reconstruction trail
- allow multiple defs to be added with same pool of removed formulas
- fix tracking of function symbols instead of expressions to filter replay
- add nla_divisions to track (cheap) divisibility lemmas.
-
Fix src/util/hwf.cpp for building with MinGW-w64 clang targetting Windows 32-bit.
Without this fix there is an arror about `__control87_2` not being defined.
other updates:
- change signature of advance_qhead to simplify call sites
- have model reconstruction replay work on a tail of dependent_expr state, while adding formulas to the tail.
the solve_eqs_tactic is to be replaced by a re-implementation that uses solve_eqs in the simplifiers directory.
The re-implementation should address efficiency issues with the previous code.
At this point it punts on low level proofs. The plan is to use coarser
dependency tracking instead of low level proofs for pre-processing. Dependencies can be converted into a proof hint representation that can be checked using a stronger checker.
