strings as default.
  [Feature #11725]

* insns.def (freezestring): add new instruction to support adding
  debug information for dynamically constracted strings.

* compile.c (iseq_compile_each): support adding debug information
  for NODE_DSTR with freezestring instruction.

* error.c (rb_error_frozen): change the debug information ID name
  id_debug_created_info and this field should have a 2 element array
  containing path and line information.

* defs/id.def: ditto.

* test/ruby/test_rubyoptions.rb: catch up this fix.

* test/ruby/test_iseq.rb: now frozen strings are not same.
