James Zern
8043504f95 lossless*sse2: improve non-const 16-bit vector creation 
use _mm_set1_epi32 instead of _mm_set_epi16 with non-const values;
reduces shifts and ors.

55403a9a5a Upsampling SSE2/SSE4 speedup. 
RGB to YUV conversion was not using SSE to finish up the row.
End data is now copied to a buffer big enough to fit in a
SSE register.
(UPSAMPLE_LAST_BLOCK was already using that trick).

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.
