Nikolaj Bjorner fdd5c923ed use only maxres if there is a lexicographic objective, fix #6697

Nikolaj Bjorner f8242c58dd fix regression from Grobner port 
- scan_for_linear returns true if it finds a new linear equation. It then should break GB.
- if scan_for_linear returns false, it should still allow try_modify_eqs.
This behavior was masked by requiring scan_for_linear to always be true before
allowing try_to_modify_eqs.

based on repro from Guido Martinez @mtzguido

Nikolaj Bjorner a62e4b2893 extract multi-patterns when pattern can be decomposed 
deals with fluke regression for F* reported by Guido Martinez

Background:
The automatic pattern inference facility looks for terms that contains all bound variables of a quantifier. It may end up with a term that contains all bound variables but the extracted term can be simplified.

Example. The pattern

(ApplyTT (ApplyTT @x3!1 (ApplyTT @x4!0 (:var 1))) (ApplyTT @x4!0 (:var 0)))
can be decomposed into a multi-pattern
(ApplyTT @x4!0 (:var 1))) (ApplyTT @x4!0 (:var 0))
The multi-pattern may enable a quantifier instantiation while the original pattern does not. The multi-pattern should be preferred.

The regression showed up based on a change that should not be considered harmful but turned out to be noticeable.
The change was a simplification of and-or expressions based on sorting. This played with the case split queue used by F* (smt.case_split = 3) that uses a top-level case split of clauses to avoid redundant branches. The net effect was that without sorting, the benchmarks would always choose the opportune branch that enabled matching against the larger term. With sorting it would mostly choose inopportune branches.
