destructive equality resolution uses an occurs check function that is only safe for quantifier-free formulas. In the special case where a bound variable is Boolean and occurs on a side of an equality the other side cannot have a quantifier.

2bff0a6b8a regression on quantifier weight computation when weights are 0 vs non-0. It modifies a change made for the fix of #2667. That fix caused a regression in F*. Reported @mtzguido

68f43ac7a4 make der selective to configuration. For F*, quantifiers are hand or machine generated in specific formats and the tool depends on e-matching to use precisely the format of the quantifiers that have been entered. For other cases of quantifiers, destructive equality resolution (der) can be expected to offer simplifications

Implement proposed smtlib2 bitvector overflow predicates (#6715) 
* Logical names for function declarations in c++

Currently, for example, the function declaration symbol member for
checking whether multiplication *does not* overflow is called
`m_bv_smul_ovfl`.  Since we are introducing the upcoming smtlib2 symbols
that check that multpliciation *does* overflow, the not overflow check
symbols are renamed to `m_bv_smul_no_ovfl` etc.

* Implement smtlib overflow preds for multiplication

Smtlib2 is being extended to include overflow predicates for bit
vectors (see https://groups.google.com/u/1/g/smt-lib/c/J4D99wT0aKI).
This commit introduces the predicates `bvumulo` and `bvsmulo` that
return `true` if the unsigned multiplication overflows or the signed
multiplication underflows or overflows, respectively.

* Move mul overflow predicates to BV logic

* Add a todo on illogical argument order

* Implement mk_unary_pred for bv

* Implement bvnego

* Implement bvuaddo

* Implement bvsaddo

* Implement bvusubo

* Implement bvssubo

* Implement bvsdivo
