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.

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
