Title: YUV2RGB fix for undefined behavior.

Two of the constants passed to SSE_COEFFICIENTS are negative according to the defines at the top of the file, but the left shift should clear the sign bit. GCC accepts the shift just fine, but Clang throws an error, so just multiply by 4 to be explicit and silence clang.
