Reuse RelocInfo's IsPatchedDebugBreakSlotSequence() implementation.

RelocInfo::IsPatchedDebugBreakSlotSequence() already does this assembly
check, so just reuse it in BreakLocationIterator::IsDebugBreakAtSlot(),
like the other debug ports do.

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;
        }
    })();
