* tool/make-snapshot: use ENV["AUTOCONF"] instead of directly using
  literal "autoconf".

* hash.c (rb_hash_tbl_raw), internal.h: added.
  Returns st_table without shading hash.
* array.c: use rb_hash_tbl_raw() for read-only purpose.

* gc.c (count_objects): ditto.
* insns.def: ditto.
* process.c: ditto.

* gc.c (gc_stat): collect shade_operation_count,
  remembered_sunny_object_count and remembered_shady_object_count
  for each types when RGENGC_PROFILE >= 2.
  They are informative for optimization.

  types (RGENGC_PROFILE >= 2).

* include/ruby/debug.h, vm_trace.c: add rb_postponed_job API.
  Postponed jobs are registered with this API. Registered jobs
  are invoked at `ruby-running-safe-point' as soon as possible.
  This timing is completely same as finalizer timing.
  There are two APIs:
* rb_postponed_job_register(flags, func, data): register a
  postponed job with data. flags are reserved.
* rb_postponed_job_register_one(flags, func, data): same as
  `rb_postponed_job_register', but only one `func' job is
  registered (skip if `func' is already registered).
  This change is mostly written by Aman Gupta (tmm1).
  https://bugs.ruby-lang.org/issues/8107#note-15
  [Feature #8107]
* gc.c: use postponed job API for finalizer.
* common.mk: add dependency from vm_trace.c to debug.h.
* ext/-test-/postponed_job/extconf.rb, postponed_job.c,
  test/-ext-/postponed_job/test_postponed_job.rb: add a test.
* thread.c: implement postponed API.
* vm_core.h: ditto.

* include/ruby/ruby.h, gc.c, vm_trace.c: add internal events.
* RUBY_INTERNAL_EVENT_NEWOBJ: object created.
* RUBY_INTERNAL_EVENT_FREE: object freeed.
* RUBY_INTERNAL_EVENT_GC_START: GC started.
  And rename `RUBY_EVENT_SWITCH' to `RUBY_INTERNAL_EVENT_SWITCH'.
  Internal events can not invoke any Ruby program because the tracing
  timing may be critical (under huge restriction).
  These events can be hooked only by C-extensions.
  We recommend to use rb_potponed_job_register() API to call Ruby
  program safely.

* include/ruby/debug.h, vm_trace.c: added two new APIs.
* rb_tracearg_event_flag() returns rb_event_flag_t of this event.
* rb_tracearg_object() returns created/freeed object.

  ext/-test-/tracepoint/tracepoint.c,
  test/-ext-/tracepoint/test_tracepoint.rb: add a test.
