cc6769c866 improve bit-blasting for the case (bvsrem var power-of-two) 
We will now transform bvsrem into an extract + zero extend
Gives ~40% speedup in selected benchmarks

cec328cfdc Add get_sort(expr * n) function that does not depend on ast_manager. Move power_of_two to rational class. Add arith_recognizers and bv_recognizers classes. The two new classes contain the 'read-only' methods from arith_util and bv_util.
