f27f773576 lossless_neon: enable VP8LAddGreenToBlueAndRed 
this moves the function outside the WEBP_USE_INTRINSICS check.
there's no alternative version and it's ~70% faster at the
function level and 1-2% faster overall

involved, but overall it's faster.

Removed the SSE4.1 implementation which is now slower than SSE2.

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.

Visible speed-up, thanks to pshufb and pabsw and psignw use.

had to tweak configure.ac to make "smmintri.h" presence correctly
detected (we need to set the CPPFLAGS instead of the CFLAGS!)
