* eval.c (avalue_to_svalue): use rb_check_array_type() again.

  Clarify how "to_ary" and "to_a" work. [ruby-talk:68155]

* eval.c (svalue_to_avalue): ditto.

* eval.c (svalue_to_mrhs): ditto.

* eval.c (rb_eval): unary splat to use to_a, but we need a hack to
  exclude Object#to_a until it's removed.

* object.c (rb_Array): check obj.respond_to?("to_a").  Currently
  all object respond_to "to_a", but Object#to_a will be removed.

* range.c (Init_Range): undefine to_ary.

* re.c (Init_Regexp): ditto.

* regex.c (re_compile_pattern): do not warn if "-" is at the top
  or last of character class.
