During compaction we must fix up shapes on objects who were extended but
then became embedded. `rb_shape_traverse_from_new_root` is supposed to
walk shape trees looking for a matching shape. When a shape has a
"single child" we weren't returning NULL when the edge names didn't
match.
In the case of a single outgoing edge, this patch returns NULL when the
child edge name doesn't match (similar to the case when a shape has a
hash of outgoing edges)
yjit-trace-exits appends a synthetic sample for the instruction being
exited, but we didn't increment the size of the stack. Fixing this count
correctly lets us successfully generate a flamegraph from the exits.
I also replaced the line number for instructions with 0, as I don't
think the previous value had meaning.

On platforms where unaligned word access is not allowed, and if
`sizeof(val)` and `sizeof(type)` differ:
- `val` > `type`, `val` will be a garbage.
- `val` < `type`, outside `val` will be clobbered.
ruby/test_default_gems.rb can define empty `DidYouMean` module
because of the following line (second require) in the
`lib/did_you_mean/did_you_mean.gemspec`:
```ruby
begin
require_relative "lib/did_you_mean/version"
rescue LoadError # Fallback to load version file in ruby core repository
require_relative "version"
end
```
It defines only `::DidYouMean::VERSION`.
However, in the `test/ruby/test_patten_matching.rb` assumes that
if `defined?(DidYouMean)` is true, then there is a method `DidYouMean.formatter=`
and this assumption fails all tests in `test/ruby/test_patten_matching.rb` if
there is only a `::DidYouMean::VERSION`.
To reproduce the failures, we need to repeat the following command:
`make test-all TESTS='-v ruby/test_default_gems.rb ruby/pattern_matching'`
(because the ruby/test_default_gems.rb should be run before the ruby/pattern_matching`)
This patch introduces more strict gurds.
Previously, setinstancevariable could generate code that calls
`rb_ensure_iv_list_size()` without first updating `cfp->sp`. This means
in the event that a GC start from within said routine the top few
objects would not be marked, causing them to be falsly collected.
Call `jit_prepare_routine_call()` first.

RB_WARN_CATEGORY_ALL_BITS is exposed in a public header, so it
makes sense for it to be updated to contain all valid bits.
Instead we introduce RB_WARN_CATEGORY_DEFAULT_BITS to list the
categories that are enabled by default.
Rebuilding the loaded feature index slowed down with the bug fix
for #17885 in 79a4484a07. The
slowdown was extreme if realpath emulation was used, but even when
not emulated, it could be about 10x slower.
This adds loaded_features_realpath_map to rb_vm_struct. This is a
hidden hash mapping loaded feature paths to realpaths. When
rebuilding the loaded feature index, look at this hash to get
cached realpath values, and skip calling rb_check_realpath if a
cached value is found.
