b94cee98fb dec_sse2: remove HE8uv_SSE2 
with gcc-4.8, clang-4.0.1/5 this is no faster (actually up to 2x slower)
than the code generated for memset (0x01010... * dst[-1]). shuffles in
sse4 recover a bit, but performance is still down.

b7971d0e22 dsp: avoid defining _C functions w/NEON builds 
when targeting NEON C functions with NEON equivalents won't be used, but
will contribute to binary size. the same goes for sse2, etc., but this
change is primarily concerned with binary sizes for android arm targets.

note '-noasm' or otherwise modifying VP8GetCPUInfo will have no effect
on the use of NEON functions.

this decision can be overridden by defining WEBP_DSP_OMIT_C_CODE to 0.

4105d565d3 disable WEBP_USE_XXX optimisations when EMSCRIPTEN is defined 
Currently, none are available. If WEBP_HAVE_SSE2 eventually works,
we'll have to refine this conditionals.

especially for arm64.

9b3aca404d NEON: fix overflow in SSE NxN calculation 
vmlal_u8() is prone to overflow during the accumulation.
There was a mismatch happening at low q mostly. Because in this
case the distortion is important and the accumulated sum was
later than 16bit-unsigned.
