9699b3a2d7 mss12: avoid unnecessary division in arith*_get_bit() 
That division can be replaced with a comparison:
((c->value - c->low) << 1) + 1 >= range

By expanding 'range' definition and simplifying this inequation we obtain
the final expression.

Suggested by Michael Niedermayer <michaelni@gmx.at>
