Memory allocation in dot product

[Frisus95]

I think I found myself the answer in the documentation of https://github.com/JuliaSIMD/LoopVectorization.jl#dot-product

function mydotavx(A)
          s = 0.0
          @turbo for i ∈ eachindex(A)
              s += A[i]*A[i]
          end
          s
      end

@btime mydotavx($A)

  105.684 ns (0 allocations: 0 bytes)
