Code Releases Activity

add debug counters more.

Browse source 
* debug_counter.h: add the following counters.
  * frame_push: control frame counts (total counts).
  * frame_push_*: control frame counts per every frame type.
  * obj_*: add free'ed counts for each type.

* gc.c: ditto.

* vm_insnhelper.c (vm_push_frame): ditto.

* debug_counter.c (rb_debug_counter_show_results): widen counts field
  to show >10G numbers.
