776a509891 [AArch64] Unroll ScaleRowDown34_1_Box_NEON 
We can make use of wider instructions for the loads and stores as well
as the URHADD instructions. In addition the duplicated instructions of
the code from the unrolling provides a further small improvement for
little cores with limited out-of-order capability.

Reduction in runtimes observed compared to the existing Neon
implementation:

 Cortex-A55: -23.5%
Cortex-A510: -35.4%
Cortex-A520: -40.5%
 Cortex-A76: -15.1%
Cortex-A715:  -6.2%
Cortex-A720:  -6.2%
  Cortex-X1: -17.9%
  Cortex-X2: -18.4%
  Cortex-X3: -18.3%
  Cortex-X4: -14.0%

be5de19db3 [AArch64] Unroll ScaleRowUp2_Linear_NEON 
On little cores with limited out-of-order capability this gives a good
improvement.

Reduction in runtimes observed compared to the existing Neon
implementation:

 Cortex-A55: -21.3%
Cortex-A520: -33.6%
 Cortex-A76:  +1.1%
Cortex-A715:  =0.0%
Cortex-A720:  =0.0%
  Cortex-X1: +10.4% (!)
  Cortex-X2:  -5.3%
  Cortex-X3:  -4.3%
  Cortex-X4:  -9.9%

98ec7c28d5 Fix SSE2 version of ScalePlaneUp2_16_Bilinear 
- Define HAS_SCALEROWUP2_BILINEAR_16_SSE2: it's now fixed.
- Correct function name to ScaleRowUp2_Bilinear_16_Any_SSE2:
   this row function uses only SSE2 instructions.

05416e2d9a Box filter for YUV use rows with accumulation buffer for better memory behavior. The old code would do columns accumulated into registers, and then store the result once. This was slow from a memory point of view. The new code does a row of source at a time, updating an accumulation buffer every row. The accumulation buffer is small, and should fit cache. Before each accumulation of N rows, the buffer needs to be reset to zero. If the memset is a bottleneck, it would be faster to do the first row without an add, storing to the accumulation buffer, and then add for the remaining rows.
