This is a reland of 35a74eab5d
Added guard for SKNX_NO_SIMD. I guess they don't want speedy goodness.
Original change's description:
> add a scaled uint32x4_t divided by uint32_t to SkVx
>
> This extracts the divide used in SkImageBlurFilter.cpp, and
> encapsulates it into ScaledDividerU32. It generates results that
> are with in +/- 1 of the rounded answer generated by doubles.
>
> I have added hand coded implementations for sse and for neon to
> hopefully to avoid code generation problems.
