Subject: * eval.c (is_defined): should not dump core for "defined?(())".

* eval.c (umethod_bind): recv can be an instance of descender of
  oklass if oklass is a Module.

* hash.c (rb_hash_equal): check identiry equality first.

* file.c (group_member): should check real gid only.

* file.c (eaccess): do not cache euid, since effective euid may be
  changed via Process.euid=().

* file.c (eaccess): return -1 unless every specified access mode
  is permitted.

* eval.c (rb_eval): while/until returns the value which is given
  to break.

* parse.y (value_expr): using while/until/class/def as an
  expression is now gives a warning, not an error.

* range.c (range_eqq): should compare strings based on magical
  increment (using String#upto), not dictionary order.

* enum.c (enum_sort_by): new method for Schewartzian transformed
  stable sort.

* variable.c (mod_av_set): detect constant overriding for built-in
  classes/modules.
