Merge pull request #6938 from Z3Prover/uprop 
fix a bug in unit nl prop. This also speeds up the nl propagation by more than 20 percent.

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

simplify assumptions and only replay assumptions after constraints are simplified. This allows simplifying assumptions with the current set of constraints independently of whether there is another check-sat.
