	* parse.y (parse_ident): just after a label, new expression should
	  start, cannot be a modifier.  [ruby-core:65211] [Bug #10279]

	* string.c (setup_fake_str): fake strings should not set class by
	  RBASIC_SET_CLASS() because it insert write barriers to fake
	  (non-RVALUE) structure.
	  It can cause unexpected behaviour.
	  Ruby 2.1 also have a same problem (setup_fake_str() in parse.y).

	* symbol.c (setup_fake_str): ditto.

	* parse.y (lex_state_e, parser_params, f_arglist, parser_yylex):
	  separate EXPR_LABELARG from EXPR_BEG and let newline significant,
	  so that required keyword argument can place at the end of
	  argument list without parentheses.  [ruby-core:61658] [Bug #9669]

	test_method.rb, test_proc.rb: suppress warnings

	* test/ruby/test_method.rb: suppress warnings in verbose mode.

	* test/ruby/test_proc.rb: ditto.
	* proc.c (rb_iseq_min_max_arity): maximum argument is unlimited if
	  having rest keywords argument.  [ruby-core:53298] [Bug #8072]

	* iseq.c (rb_iseq_parameters): push argument type symbol only for
	  unnamed rest keywords argument.

	* compile.c (iseq_set_arguments): set arg_keyword_check from

	  keyword check.

	* iseq.c (rb_iseq_parameters): if no keyword check, keyword rest is
	  present.

	* parse.y (new_args_tail_gen): set keywords check to nd_cflag, which
	  equals to that keyword rest is not present.
