Implement SSE2-based implementations of the morphology filters (dilate & erode). This gives a 3-5X speedup over the naive implementation, and also mitigates a timing-based security attack in Chrome (https://code.google.com/p/chromium/issues/detail?id=251711).
NOTE: this will require a corresponding GYP change on the Skia roll into Chrome: https://codereview.chromium.org/52453004/
