8404253f81 Fix bugs in convolution filter optimization 
- Fix the over-writing bug in horizontal filtering as width = 2.
- Fix 10-tap vertical filtering which no longer reads one row of
  pixel above the block.
- Fix 10-tap filter zero padding.
- Encoder speed slow down ~4.0%, compared to,
  81ad953 Convolution vertical filter SSSE3 optimization

81ad95363a Convolution vertical filter SSSE3 optimization 
- Apply 8-pixel vertical filtering direction parallelism.
- Add unit tests to verify bit exact.
- Encoder speed improves ~29% (enable EXT_INTERP) on Xeon E5-2680.
- Combinational cycle count of vp10_convolve() drops from 26.06%
  to 6.73%.
