zero extended; mildly faster at the function level

acd7b5af0f Introduce a test tool anim_diff. 
It can be used to test if given pair of animated images (GIF and/or
WebP) are identical in terms of pixel match and other animation
properties.

0e009366f8 dsp/cpu.c(x86): check maximum supported cpuid feature

detecting avx2 on some older processors that support avx.
for completeness also check for value=1 support used by the other
checks.

7fe357b8c0 split 64-mult hashing into two 32-bit multiplies 
Speed-wise equivalent on x86 and ARM (maybe a tad faster, hard to tell).

Note that the two 32-bit multiples are not strictly equivalent
to the 64-bit one, since we're missing one carry propagation.
In practice, no observable difference was seen because of this
slightly different hashing result.
