Reland "For runtime shaders, deduce isOpaque automatically"

This is a reland of 995d16fc910219213755e924901c66b2a7c836a9

Original change's description:
> For runtime shaders, deduce isOpaque automatically
>
> The forceOpaque parameter is now ignored. Instead, we do a conservative
> analysis of the shader's main function to determine if it always returns
> an opaque color. This is good enough to detect simple cases, including
> things like:
>
>   return child.eval(p).rgb1
