I caught a reproduction of this test failing under rr, and was able to
replay it to isolate the failure. The call to
`before_stat_heap = GC.stat_heap` is itself allocating a hash, which in
unlucky circumstances can result in a new page being allocated and thus
`before_stats[:heap_allocated_pages]` no longer equals
`after_stats[:heap_allocated_pages]`.
The solution is to use the form of GC.stat/stat_heap which takes a hash
as an argument, and thus needs to perform no Ruby allocations itself.
If a gem package is built from a specification whose platform has been
modified, it will include metadata using the old platform.
This change should fix the problem by making sure `original_platform` is
always properly set.

When using the `bundler/setup` entrypoint, Bundler prints the following
warnings in JRuby in `-w` is passed to Ruby.
```
/path/to/bundler/shared_helpers.rb:10: warning: constant Bundler::WINDOWS is deprecated
/path/to/bundler/shared_helpers.rb:11: warning: constant Bundler::FREEBSD is deprecated
/path/to/bundler/lib/bundler/shared_helpers.rb:12: warning: constant Bundler::NULL is deprecated
```
This does not happen in CRuby.
This seems like a JRuby bug but we can skip it by autoloading the
constants.

Fix as the compiler orders:
```
warning: unused return value of `into_raw_fd` that must be used
--> ../src/yjit/src/disasm.rs:123:21
|
123 | file.into_raw_fd(); // keep the fd open
| ^^^^^^^^^^^^^^^^^^
|
= note: losing the raw file descriptor may leak resources
= note: `#[warn(unused_must_use)]` on by default
help: use `let _ = ...` to ignore the resulting value
|
123 | let _ = file.into_raw_fd(); // keep the fd open
| +++++++
warning: unused return value of `into_raw_fd` that must be used
--> ../src/yjit/src/log.rs:84:21

84 | file.into_raw_fd(); // keep the fd open
| ^^^^^^^^^^^^^^^^^^

= note: losing the raw file descriptor may leak resources
help: use `let _ = ...` to ignore the resulting value

```
to show unused block warning strictly.
```ruby
class C
def f = nil
end
class D
def f = yield
end
[C.new, D.new].each{|obj| obj.f{}}
```
In this case, `D#f` accepts a block. However `C#f` doesn't
accept a block. There are some cases passing a block with
`obj.f{}` where `obj` is `C` or `D`. To avoid warnings on
such cases, "unused block warning" will be warned only if
there is not same name which accepts a block.
On the above example, `C.new.f{}` doesn't show any warnings
because there is a same name `D#f` which accepts a block.
We call this default behavior as "relax mode".
`strict_unused_block` new warning category changes from
"relax mode" to "strict mode", we don't check same name
methods and `C.new.f{}` will be warned.
[Feature #15554]
This is somewhat dead code as unless you are using `JSON::Parser.new`
direcltly we never allocate `JSON::Ext::Parser` anymore.
But still, we should mark all its reference in case some code out there
uses that.
Followup: #675https://github.com/ruby/json/commit/8bf74a977b
Mingw crt-git 12.0.0.r369.g0d4221712-1 now prohibits "command line
contains characters that are not supported in the active code page".
0d42217123/
Already Ruby builds `argv` in `rb_w32_sysinit`, instead of mswin- or
mingw-made `argv`. Just bypass the conversion in mingw crt.
rb_fiber_scheduler_current() may return nil depending on whether the
scheduler is being prevented for some reason, e.g., Fiber.blocking{}.
