    file.c: rb_check_realpath

    * file.c (rb_check_realpath): returns real path which has no
      symbolic links.  similar to rb_realpath except for returning
      Qnil if any parts did not exist.

    load.c: real path to load

    * load.c (rb_construct_expanded_load_path): expand load paths to
      real paths to get rid of duplicate loading from symbolic-linked
      directories.  [Feature #10222]
