'''Mozilla-specific things.'''
Nanojit's CSE pass commons up the repetitive index computations beautifully. Using an integer-only version of Math.abs() is easy and makes things much faster ([https://bugzilla.mozilla.org/show_bug.cgi?id=606441 bug 606441]).
Again, similar to imaging-desaturate, because the array-of-ints becomes an array-of-doubles, the tracer generates code assuming it's always an array-of-ints, and so the fragment for the inner loop frequently (about 50% of the time) side-exits to a secondary fragment.
All the integer overflow checks hurt. Removing them (unsafe in general, ok for this benchmark) makes it 1.27x faster.
