Subject: [ruby-core:120082] [Ruby master Bug#20927] `{ **{ } }` behaves differently when `shareable_constant_value: experimental_everything`

Issue #20927 has been reported by tenderlovemaking (Aaron Patterson).

----------------------------------------
Bug #20927: `{ **{ } }` behaves differently when `shareable_constant_value: experimental_everything`
https://bugs.ruby-lang.org/issues/20927

* Author: tenderlovemaking (Aaron Patterson)
* Status: Open
* ruby -v: ruby 3.3.4 (2024-07-16 revision 425e468d25) [arm64-darwin23]
* Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
These two programs produce different results

```ruby
# shareable_constant_value: experimental_everything

C = { **{ } }

p C
```

```ruby
C = { **{ } }

p C
```

The first one prints this:

```
$ ruby test.rb
{nil=>{}}
```

The second one prints this:

```
$ ruby test.rb
{}
```

I think they should print the same thing.
