Michael Ludwig c26cf6c2f5 Guard against width/height overflow in SkIRect::subtract 
SkRectPriv::Subtract had assumed that Sk[I]Rect::Intersects returns
false if either argument is empty. However, when an SkIRect with
overflowing dimensions is intersected with a non-overflowing SkIRect,
then the intersection can be valid and the remainder of the impl's
expectations are violated because dimensions are "negative".

Since these overflowing rects are considered empty anyways, this just
explicitly checks for that.
