* eval.c (is_defined): defined?(Foo::Baz) should check constants

  only, no methods.

* eval.c (is_defined): should not dump core on defined?(a::b)
  where a is not a class nor a module.

* object.c (Init_Object): remove dup and clone from TrueClass,
  FalseClass, and NilClass.

* array.c (rb_ary_fill): Array#fill takes block to get the value to
  fill.

* string.c (rb_str_to_i): to_i(0) auto-detects base radix.

* array.c (rb_ary_initialize): fill by the block evaluation value
  if block is given.
