* include/ruby/ruby.h (struct RClass): Add wrapper struct around
  RClass->m_tbl with serial. This prevents double marking method
  tables, since many classes/modules can share the same method table.
  This improves minor mark time in a large application by 30%.
* internal.h (struct method_table_wrapper): Define new
  wrapper struct with additional serial.
* internal.h (RCLASS_M_TBL_INIT): New macro for initializing method
  table wrapper and st_table.
* method.h (void rb_sweep_method_entry): Rename rb_free_m_table to
  rb_free_m_tbl for consistentcy
* .gdbinit (define rb_method_entry): Update rb_method_entry gdb helper
  for new method table structure.
* class.c: Use RCLASS_M_TBL_WRAPPER and
  RCLASS_M_TBL_INIT macros.
* class.c (rb_include_class_new): Share WRAPPER between module and
  iclass, so serial can prevent double marking.
* eval.c (rb_prepend_module): ditto.
* eval.c (rb_using_refinement): ditto.
* gc.c: Mark and free new wrapper struct.
* gc.c (obj_memsize_of): Count size of additional wrapper struct.

* load.c (features_index_add_single): Move loaded_features_index array values off

* load.c (loaded_features_index_clear_i): Clean up off-heap array structure.
* vm.c (rb_vm_mark): Remove unnecessary mark_tbl for loaded_features_index.
  This improves minor GC time by 15% in a large application.

hash.c: same hash value for similar constructs

* hash.c (rb_hash_recursive): make similar (recursive) constructs
  return same hash value.  execute recursively, and rewind to the
  topmost frame with an object which .eql? to the recursive
  object, if recursion is detected.

* string.c (fstr_update_callback): Improve implementation in r43968
  based on feedback from @nagachika. In the existing case, we can
  return ST_STOP to prevent any hash modification. In the !existing
  case, set both key and value to the fstr.
