RGenGC is designed as 2 generational GC, young and old generation.
Young objects will be promoted to old objects after one GC.
Old objects are not collect until major (full) GC.
The issue of this approach is some objects can promoted as old
objects accidentally and not freed until major GC.
Major GC is not frequently so short-lived but accidentally becoming
old objects are not freed.
For example, the program "loop{Array.new(1_000_000)}" consumes huge
memories because short lived objects (an array which has 1M
elements) are promoted while GC and they are not freed before major
GC.
To solve this problem, generational GC with more generations
technique is known. This patch implements three generations gen GC.
At first, newly created objects are "Infant" objects.
After surviving one GC, "Infant" objects are promoted to "Young"
objects.
"Young" objects are promoted to "Old" objects after surviving
next GC.
"Infant" and "Young" objects are collected if it is not marked
while minor GC. So that this technique solves this problem.
Representation of generations:
* Infant: !FL_PROMOTED and !oldgen_bitmap [00]
* Young : FL_PROMOTED and !oldgen_bitmap [10]
* Old : FL_PROMOTED and oldgen_bitmap [11]
The macro "RGENGC_THREEGEN" enables/disables this feature, and
turned off as default because there are several problems.
(1) Failed sometimes (Heisenbugs).
(2) Performance down.
Especially on write barriers. We need to detect Young or Old
object by oldgen_bitmap. It is slower than checking flags.
To evaluate this feature on more applications, I commit this patch.
Reports are very welcome.
This patch includes some refactoring (renaming names, etc).
* include/ruby/ruby.h: catch up 3gen GC.
* .gdbinit: fix to show a prompt "[PROMOTED]" for promoted objects.

freed at finalizaton point.

ruby_vm_global_state_version into two separate counters - one for the
global method state and one for the global constant state. This means
changes to constants do not affect method caches, and changes to
methods do not affect constant caches. In particular, this means
inclusions of modules containing constants no longer globally
invalidate the method cache.
* class.c, eval.c, include/ruby/intern.h, insns.def, vm.c, vm_method.c:
rename rb_clear_cache_by_class to rb_clear_method_cache_by_class
* class.c, include/ruby/intern.h, variable.c, vm_method.c: add
rb_clear_constant_cache
* compile.c, vm_core.h, vm_insnhelper.c: rename vmstat field in
rb_call_info_struct to method_state
