Subject: Fix that large integer is not GCed with Word-boxing

### Example (32-bit Word-boxing)

  ```ruby
  # example.rb
  int_count = ObjectSpace.count_objects[:T_INTEGER]||0
  int = 1<<30
  p (ObjectSpace.count_objects[:T_INTEGER]||0) - int_count
  int = nil
  GC.start
  p (ObjectSpace.count_objects[:T_INTEGER]||0) - int_count
  ```

#### Before this patch:

  ```console
  $ bin/mruby example.rb
  1
  1
  ```

#### After this patch:

  ```console
  $ bin/mruby example.rb
  1
  0
  ```
