MIPS: Fixed flooring division by a power of 2, once again...

Port r21769 (52e191b)

Original commit message:
Avoid right shifts by zero bits: On ARM it actually means shifting by
32 bits (correctness issue) and on other platforms they are useless
(performance issue). This is fix for the fix in r20544.
