blas64: order of fields in exported structs

[vladimir-ch]

The order of fields in structs like Vector or General should follow the order in which they typically appear in a function call. This would make more natural and easier to understand calls with inline declarations with unnamed fields. For example, in case of Vector and Dscal:

native.Implementation{}.Dscal(n, scale, x, 1)
vs.
blas64.Scal(n, scale, blas64.Vector{1, x})

Similarly for General and other types.
