…le/2 (#9864)

This was the documented behaviour on 1.9 that was broken on v1.10: (version `git` is this branch)

    $ cat a.ex
    defmodule A, do: nil

    $ for v in 1.9.4-otp-22 1.10.2-otp-22 git; do asdf local elixir $v && echo $v; elixir -e 'IO.inspect Code.compile_file("a.ex")'; done
    1.9.4-otp-22
    [{A, <<70, 79, ...>>}
    1.10.2-otp-22
    [{A, %{attributes: [], ...}]
    git
    [{A, <<70, 79, ...>>}

    $ for v in 1.9.4-otp-22 1.10.2-otp-22 git; do asdf local elixir $v && echo $v; elixir -e 'IO.inspect Code.require_file("a.ex")'; done
    1.9.4-otp-22
    [{A, <<70, 79, ...>>}]
    1.10.2-otp-22
