sizehint! ineffective for RobinDict

[dantaras]

julia> function check_alloc(d, n)
           for i in 1:n
               a = @allocated d[i] = i
               println(i, " ", a)
           end
           nothing
       end
check_alloc (generic function with 1 method)

julia> check_alloc(sizehint!(RobinDict{Int, Int}(), 16), 16)

The root cause is here https://github.com/JuliaCollections/DataStructures.jl/blob/f90dd8ceb1808123136d96599fbf41407ef4fadc/src/robin_dict.jl#L200-L201 which should instead be:

        resize!(h.keys, newsz)
        resize!(h.vals, newsz)
