Remove unnecessary calculation in 4-tap interpolation filter
Reduces the number of rows calculated for 2D 4-tap interpolation filter
from h+7 rows to h+3 rows.
Also fixes a bug in the avx2 function for 4-tap filters where the last
row is computed incorrectly.
Performance:
| Baseline | Result | Pct Gain |
bitdepth lo| 4.00 fps | 4.02 fps | 0.5% |
bitdepth 10| 1.90 fps | 1.91 fps | 0.5% |
The performance is evaluated on speed 1 on jets.y4m br 500 over 100
frames.
No BDBR loss is observed.
