* gc.c (check_bitmap_consistency): add to check flag and bitmap consistency.
  Use this function in several places.

* gc.c (slot_sweep_body): rename to slot_sweep().
  No need to separate major/minor GC.
* gc.c (gc_setup_mark_bits): remove gc_clear_mark_bits() and unify to
  this function.

* include/ruby/ruby.h (OBJ_WRITE): cast to (VALUE *) for second
  parameter `slot'. You don't need to write a cast (VALUE *) any more.
* class.c, compile.c, hash.c, iseq.c, proc.c, re.c, variable.c,
  vm.c, vm_method.c: remove cast expressions for OBJ_WRITE().

* gc.c (rgengc_rememberset_mark): call gc_mark_children() for
  remembered objects directly instead of pushing on the mark stack.

* gc.c (rb_gc_giveup_promoted_writebarrier): remove `rest_sweep()'
  because all of remembered objects are called for gc_mark_children().



git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@41550 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* gc.c (rb_objspace::profile): rename rb_objspace::profile::record to
  records (because it points a set of records) and add a field
  rb_objspace::profile::current_record to point a current profiling
  record.
* gc.c: use above fields.



git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@41551 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* gc.c (gc_prof_set_heap_info, after_gc_sweep): call
  gc_prof_set_heap_info() just after sweeping to calculate
  live object number correctly.
  (live object number = total generated number (before marking) -
                        total freed number (after sweeping))
* gc.c (gc_marks): record `oldgen_object_count' into current profile`
  record directly.
* gc.c (rgengc_rememberset_mark): same for remembered_normal_objects
  and remembered_shady_objects.
