arm: Add NEON implementations of splat_mv
Relative speedup over C code, for arm64:
Cortex A53 A72 A73 Apple M1
splat_mv_w1_neon: 1.09 0.95 1.22 -
splat_mv_w2_neon: 1.76 1.32 1.74 -
splat_mv_w4_neon: 2.78 2.19 2.19 15.00
splat_mv_w8_neon: 3.59 2.06 2.59 12.00
splat_mv_w16_neon: 4.12 1.72 2.53 3.14
splat_mv_w32_neon: 4.07 1.60 2.40 3.00
(The resolution of the timer used on Apple M1 isn't enough to
measure the small versions of this function.)
Relative speedup over C code, for arm32:
Cortex A7 A8 A9 A53 A72 A73
splat_mv_w1_neon: 0.70 1.12 0.91 0.65 1.01 1.06
splat_mv_w2_neon: 0.94 2.16 2.01 0.99 2.52 1.63
splat_mv_w4_neon: 1.27 2.04 1.49 1.52 1.75 2.18
splat_mv_w8_neon: 1.75 2.47 1.16 2.88 1.95 2.58
splat_mv_w16_neon: 2.00 2.44 1.12 3.25 1.85 2.65
splat_mv_w32_neon: 1.43 2.28 1.19 3.55 1.77 2.65
