Pavel BorisovandGitHub b2e45ed5ea Speed up ivfflat build: use float instead of double for dot product (#180) 
calculation

On ARM this makes CPU using vector multiply-add instruction (fmadd)
instead of vector multiplication + conversion to double + addition
(fmul + fcvt + fadd) at each vector dimension.

Output of distance functions and calculations that are are done once
per vector pair are left double as this don't make speed difference
and for compatibility.
