It's an estimator for application size and could be used as a
compilation heuristic later.

This patch introduce M:N thread scheduler for Ractor system.
In general, M:N thread scheduler employs N native threads (OS threads)
to manage M user-level threads (Ruby threads in this case).
On the Ruby interpreter, 1 native thread is provided for 1 Ractor
and all Ruby threads are managed by the native thread.
From Ruby 1.9, the interpreter uses 1:1 thread scheduler which means
1 Ruby thread has 1 native thread. M:N scheduler change this strategy.
Because of compatibility issue (and stableness issue of the implementation)
main Ractor doesn't use M:N scheduler on default. On the other words,
threads on the main Ractor will be managed with 1:1 thread scheduler.
There are additional settings by environment variables:
`RUBY_MN_THREADS=1` enables M:N thread scheduler on the main ractor.
Note that non-main ractors use the M:N scheduler without this
configuration. With this configuration, single ractor applications
run threads on M:1 thread scheduler (green threads, user-level threads).
`RUBY_MAX_CPU=n` specifies maximum number of native threads for
M:N scheduler (default: 8).
This patch will be reverted soon if non-easy issues are found.
[Bug #19842]
* Add yarp/yarp_compiler.c as stencil for compiling YARP
This commit adds yarp/yarp_compiler.c, and changes the sync script
to ensure that yarp/yarp_compiler.c will not get overwritten
* [Misc #119772] Create and expose RubyVM::InstructionSequence.compile_yarp
This commit creates the stencil for a compile_yarp function, which
we will continue to fill out. It allows us to check the output
of compiled YARP code against compiled code without using YARP.
[Feature #19783]
This commit adds support for weak references in the GC through the
function `rb_gc_mark_weak`. Unlike strong references, weak references
does not mark the object, but rather lets the GC know that an object
refers to another one. If the child object is freed, the pointer from
the parent object is overwritten with `Qundef`.

---
None of those revisions actually worked for both mswin and OpenBSD at
the same time. I need more time to build something that works for both.
Scratch build on OpenBSD has been failing since 67b5f63e97.
`make; make` works though. (`make` alone doesn't work)
I have no idea what I'm doing, but I do know that this patch fixes
scratch build on an OpenBSD machine.
My best guess is that BSD make isn't capable of distinguishing foo.c vs
./foo.c in dependencies, and {$(VPATH)} becomes empty when it needs to be.
