Lucas Chollet ccdd6504f9 Kernel: Don't traverse the whole tree in find_regions_intersecting 
When using the default iterator, the region tree is traversed in
ascending order. This mean that as soon as we find a region that is
above the tested range, we can safely exit the loop.

This was a major bottleneck in test-js, with this patch the runtime goes
from 6.761s to 4.680 (using a best-of-five).
