There is no need to store the symbol and the proc given the
proc has a reference to the symbol.
This makes the cache half as small, now fitting in an object
slot, but also make it easier to allow that cache to be
used by ractors, assuming we'd make `Symbol#to_proc`
return a shareable proc.
In non-main ractors, don't use `sym_proc_cache`. It is not thread-safe
to add to this array without a lock and also it leaks procs from one
ractor to another. Instead, we create a new proc each time. If this
results in poor performance we can come up with a solution later.
Fixes [Bug #21354]
We should get the object ID for finalizers in rb_gc_impl_define_finalizer
instead of when we create the finalizer job in make_final_job because
when we are in multi-Ractor mode, object ID needs to walk the references
which allocates an identity hash table. We cannot allocate in make_final_job
because it is in a MMTk worker thread.

Allow Addrinfo objects to be shared among Ractors. Addrinfo objects are
already immutable, so I think it's safe for us to tag them as
RUBY_TYPED_FROZEN_SHAREABLE shareable too.
Allow DCE to remove some CCalls
Add `elidable` field that signals that there would be no discernible
effect if the call to the method were removed. The default is false.
As reported in <https://bugs.ruby-lang.org/issues/21340>, older autoconf
have an AC_HEADER_STDBOOL that's incompatible with C23. Autoconf 2.72
fixed the macro, but also mentions that it's obsolescent since all
current compilers have this header.
Since we require C99 [1] and VS 2015 [2], we might actually be able take
that suggestion and include stdbool.h without a check. I want to try
this on rubyci.org and will revert if this cause any issues. Not
touching AC_HEADER_STDBOOL in configure.ac for now.

Since there is `bundled_gems.rb` it is not always one. Fixes the following:
```sh
$ ruby -w -rbundler/inline -e "gemfile {}; require 'cgi'"
/home/earlopain/.rbenv/versions/ruby-dev/lib/ruby/3.5.0+0/bundled_gems.rb:59: warning: CGI library is removed from Ruby 3.5. Please use cgi/escape instead for CGI.escape and CGI.unescape features.
If you need to use the full features of CGI library, Please install cgi gem.
```
into:
```sh
$ ruby -w -rbundler/inline -e "gemfile {}; require 'cgi'"
-e:1: warning: CGI library is removed from Ruby 3.5. Please use cgi/escape instead for CGI.escape and CGI.unescape features.
If you need to use the full features of CGI library, Please install cgi gem.
```
They read like this:

The problem is that `rspec` loads `erb` for its configuration, which
loads `cgi/util` from system gems.
Then our tests change the `$LOAD_PATH` to make test gems installed in
tmp visible to `require`, and then they all require `cgi` as a
transitive dependency of `rack-test`, this time from `tmp` gems. This
causes system and test specific copies to be mixed together and these
warnings to be printed, but we have also observed failures in some tests
with errors like
> class variable @@accept_charset of CGI::Util is overtaken by CGI::Escape
This changes should also fix those failures.
The fix is to require all of `rack-test` (including `cgi`) before we
have changed the `$LOAD_PATH`. Because the `$LOAD_PATH` is unchanged,
RubyGems respects the version of `cgi` activated by RSpec, avoiding the
double loads.

Necessary changes to get tests passing are:
* Rewrite one "out of memory" error spec to not define a subclass inside
a RSpec context block. Due to some [JRuby issue], that's failing in
JRuby 10, so I rewrote the test so that the Bundler process really
goes OOM and that class definition is not necessary.
* JRuby 10, even if Ruby 3.4-compatible, has not yet adapted backtraces
to include receivers, so our tests need an special case for JRuby when
detecting a test method call inside backtraces.
* Warbler test is upgraded to use JRuby 10. Getting it to pass needs [a
PR] to warbler, so our test is temporarily pointing to that PR.

The issue was that the property that
```ruby
platform = Gem::Platform.new $string
platform == Gem::Platform.new(platform.to_s)
```
was not always true.
This property (of acchieving a fix point) is important,
since `Gem::Platform` gets serialized to a string and
then deserialized back to a `Gem::Platform` object.
If it doesn't deserialize to the same object, then
different platforms are used for the initial serialization
than subsequent runs.
I used https://github.com/segiddins/Scratch/blob/main/2025/03/rubygems-platform.rb
to find the failing cases and then fixed them.
With this patch, the prop check test now passes.
