Subject: * compile.c (iseq_compile_each): emit opt_str_freeze if the #freeze  
 method is called on a static string literal with no arguments.

* defs/id.def (firstline): add freeze so idFreeze is available

* insns.def (opt_str_freeze): add opt_str_freeze instruction which
  pushes a frozen string literal without allocating a new object if
  String#freeze is not overriden

* string.c (Init_String): define String#freeze

* vm.c (vm_init_redefined_flag): define BOP_FREEZE on String class as
  a basic operation

* vm_insnhelper.h: ditto
