Options

YUV to RGB for x64 use registers instead of memory. 

On Arm the YVU to RGB conversions move constants into registers.
This change does the same for 64 bit intel builds where additional
registers are available.
The AVX2 saves 3 instructions by because the 2nd argument needs to be a register, so a vmovdqu was avoided.

x64 builds using memory:
AVX2  I420ToARGB_Opt (3059 ms)
SSSE3 I420ToARGB_Opt (3959 ms)

Now using registers
AVX2  I420ToARGB_Opt (2906 ms)
SSSE3 I420ToARGB_Opt (3928 ms)
