enable concurrent sls with new solver core

Browse source 
allow using sls engine (for bit-vectors) with the new core.

Examples

z3 sat.smt=true tactic.default_tactic=smt /v:1 smt.sls.enable=true smt.bv.solver=0 /st C:\QF_BV_SAT\bench_10.smt2
z3 sat.smt=true tactic.default_tactic=smt /v:1 smt.sls.enable=true smt.bv.solver=2 /st C:\QF_BV_SAT\bench_10.smt2
z3 C:\QF_BV_SAT\bench_11100.smt2 sat.smt=true tactic.default_tactic=smt /v:1 smt.sls.enable=true smt.bv.solver=2 /st
