Version 4.12.2
==============
- remove MSF (Microsoft Solver Foundation) plugin
- add bound_simplifier tactic.
It eliminates occurrences of "mod" operators when bounds information
- updated propagate-ineqs tactic and implementing it as a simplifier, bound_simplifier.
It now eliminates occurrences of "mod" operators when bounds information
implies that the modulus is redundant. This tactic is useful for
benchmarks created by converting bit-vector semantics to integer
reasoning.
