b0b10ec72d 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.

f865cc044a Relax assertion in StoreBuffer::FindPointersToNewSpaceInMapsRegion 
Since r21232, maps are now a non-power-of-two size and thus don't fit
evenly into a page.  No test case, as it is somewhat difficult to get
this condition to trigger.  It is possible with this case, however:

    var result;

    (function() {
        for (var i = 0; i < 1e7; i++) {
            result = (function*() { yield 1; })();
            result.foo = 1;
