Martin Vignali had commented about using VBROADCASTI128 instead of
doubling the constants to 32 bytes for AVX2.  I incorporated that into
the updated patch.

Your checkasm patch looks good to me.  I think you could also add it
to "/tests/fate/checkasm.mak".

I'm open to either order that these could be committed.  Note there
are already a few Fate vsynth tests that will fail if v210dec gets
broken.
