  • use vaddvq_f32 instead of vpaddq_f32 and vdups_laneq_f32 in fvec_L2sqr , fvec_inner_product , and fvec_norm_L2sqr
  • implement fvec_L1 and fvec_Linf for ARM SIMD (NEON)
    • This causes performance regression, so I've droped it.
  • implement fvec_madd and fvec_madd_and_argmin for ARM SIMD (NEON)
