SkBlurImageFilter_opts: optimize NEON box_blur_double in separate loops.

Stop leaning so hard on the branch predictor, and pull the conditionals
out of the loops for box_blur_double() (NEON).  This is conceptually
the same change as https://codereview.chromium.org/1426583004/ for
the NEON double-pixel loop.
