This is best understood by looking at the change to the output:
```diff
# Insn: 0002 opt_and (stack_size: 2)
- mov rax, rsi
- and rax, rdi
- mov rsi, rax
+ and rsi, rdi
```
It's a bit awkward to match against due to how stack operands are
lowered, but hey, it's nice to save the 2 unnecessary MOVs.
The `rb_fstring(rb_enc_str_new())` pattern is inefficient because:
- It passes a mutable string to `rb_fstring` so if it has to be interned it will first be duped.
- It an equivalent interned string already exists, we allocated the string for nothing.
With `rb_enc_interned_str` we either directly get the pre-existing string with 0 allocations,
or efficiently directly intern the one we create without first duping it.
The backtick method recieves a frozen string unless it is interpolated.
Otherwise the string held in the ISeq could be mutated by a custom
backtick method.

and declare it will be removed soon.
ddtrace is still referes the API and build was failed.
See https://github.com/DataDog/dd-trace-rb/pull/3578
Maybe threre are only few users of this C-API now so we can remove
it soon.
turbo_tests 2.1.1 adds json to its dependency and the current bundler
does not take the standard library json and fails to build as a gem
before the installation.

Previously, `make test-knownbugs` crashed with `NoMethodError` due to
the failed regex match if there is a test case in KNOWNBUGS.rb.
The note about 1.8 compatibility is probably bogus as we require a way
more recent BASERUBY now.
This patch fixes an error when a default gem that will be migrated to
a bundled gem is loaded from `-r` option.
Problem
===
`bundle exec ruby -rostruct -e ''` unexpectedly raises the following error:
```console
$ ruby -v
ruby 3.4.0dev (2024-04-08T02:39:00Z master 6f7e8e278f) [arm64-darwin21]
$ bundle init && bundle install
$ bundle exec ruby -rostruct -e ''
/Users/kuwabara.masataka/.rbenv/versions/trunk/lib/ruby/3.4.0+0/bundled_gems.rb:111:in 'Gem::BUNDLED_GEMS.warning?': undefined method 'find' for nil (NoMethodError)
caller = caller_locations(3, 3).find {|c| c&.absolute_path}
^^^^^
from /Users/kuwabara.masataka/.rbenv/versions/trunk/lib/ruby/3.4.0+0/bundled_gems.rb:75:in 'block (2 levels) in Kernel#replace_require'
```
Solution
===
This patch uses a safe navigation operator to fix this problem. By this
change, the command will show the warning message correctly.
```console
$ bundle exec ruby -rostruct -e ''
warning: ostruct was loaded from the standard library, but will no longer be part of the default gems since Ruby 3.5.0. Add ostruct to your Gemfile or gemspec.
```
T_TYPES was needed once Ripper jumbled NODEs and other type
objects. However such hack was already removed.
Therefore don't need to set T_TYPES of NODE.
