* 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
