Improvements are made to the main loop of div_rem and div_rem_vartime.
r as a result of subtraction with borrow does not need to be mutable because it is not strictly speaking modified afterwards.
The declaration of from_word_mask is done twice in a similar way each time through the loop, a performance gain can be found by making a single declaration for this choice, to be reused in the two calls.
