Subject: * array.c (rb_ary_to_ary): do not use #respond_to? to detect  
 to_ary.  Just call.  [ruby-core:23738]

* eval.c (rb_check_funcall): new function with method existence
  check.  returns Qundef when the method does not exist.

* enumerator.c (enumerator_rewind): just call method, using
  rb_check_funcall().  [ruby-core:23738]

* error.c (exc_equal): ditto.

* object.c (convert_type): ditto.

* error.c (rb_name_err_mesg_new): export function.

* eval.c (make_exception): ditto.

* io.c (pop_last_hash): return early when the last argument is nil.

* io.c (rb_io_puts): treat T_STRING specially for small
  optimization.

* vm_eval.c (raise_method_missing): skip method call if possible
  using rb_method_basic_definition_p().

* vm_eval.c (method_missing): ditto.

* test/ruby/test_rubyoptions.rb (TestRubyOptions#test_debug): test
  suites changed to ignore exceptions caused by just-call policy.
