Brian Salomon c75bc031ef Clamp RGB outputs of GrYUVtoRGBEffect. 
The matrices we're using can produce very slightly out of range color
channels. This gives surprising results when in shader blending is used
for color burn and color dodge. After this change we clamp the RGB
values to 0..1 before applying premul.

Adds a GM modeled on a blink layout test that shows the problem using
SkImageMakeFromYUVAPixmaps.
