Hubert Mazur 2537fdc510 sw_scale: Add specializations for hscale 16 to 19 
Provide arm64 neon optimized implementations for hscale16To19 with
filter sizes 4, 8 and X4.

The tests and benchmarks run on AWS Graviton 2 instances.
The results from a checkasm tool are shown below.

hscale_16_to_19__fs_4_dstW_512_c: 6216.0
hscale_16_to_19__fs_4_dstW_512_neon: 2257.0
hscale_16_to_19__fs_8_dstW_512_c: 10417.7
hscale_16_to_19__fs_8_dstW_512_neon: 3112.5
hscale_16_to_19__fs_12_dstW_512_c: 14890.5
hscale_16_to_19__fs_12_dstW_512_neon: 3899.0
hscale_16_to_19__fs_16_dstW_512_c: 19006.5
hscale_16_to_19__fs_16_dstW_512_neon: 5341.2
hscale_16_to_19__fs_32_dstW_512_c: 36629.5
hscale_16_to_19__fs_32_dstW_512_neon: 9502.7
hscale_16_to_19__fs_40_dstW_512_c: 45477.5
hscale_16_to_19__fs_40_dstW_512_neon: 11552.0

(Note, the checkasm tests for these functions haven't been
merged since they fail on x86.)
