5974a2dc58 remove m_b from lar_core_solver 
the column vector is pure overhead for the way the lar solver uses lp.
Some other solver modules use column vectors b and integrate with the lp_core_solver_base. The interaction model should be reviewed.
Unused solvers should be removed to make it easier to maintain this code.
