Push a real iseq in rb_vm_push_frame_fname()
Previously, vm_make_env_each() (used during proc
creation and for the debug inspector C API) picked up the
non-GC-allocated iseq that rb_vm_push_frame_fname() creates,
which led to a SEGV when the GC tried to mark the non GC object.
Put a real iseq imemo instead. Speed should be about the same since
the old code also did a imemo allocation and a malloc allocation.
Real iseq allows ironing out the special-casing of dummy frames in
rb_execution_context_mark() and rb_execution_context_update(). A check
is added to RubyVM::ISeq#eval, though, to stop attempts to run dummy
iseqs.

Fix crash in rb_gc_register_address
[Bug #19584]
Some C extensions pass a pointer to a global variable to
rb_gc_register_address. However, if a GC is triggered inside of
rb_gc_register_address, then the object could get swept since it does
not exist on the stack.

rb_feature_p: skip `get_expanded_load_path` for absolute paths
Ref: https://github.com/fxn/zeitwerk/pull/308
```ruby
require 'benchmark'
$LOAD_PATH << 'relative-path'
autoload :FOO, '/tmp/foo.rb'
puts Benchmark.realtime {
500_000.times do
Object.autoload?(:FOO)
end
}
```
The above script takes 2.5 seconds on `master`, and only
50ms on this branch.
When we're looking for a feature with an absolute path, we don't
need to call the expensive `get_expanded_load_path`.

[Bug #21144] Win32: Use Windows time zone ID if TZ is not set
If the TZ environment variable is not set, the time zone names
retrieved from the system are localized for UI display and may vary
across editions and language packs for the same time zone.
Use the time zone IDs that are invariant across environments instead.
[Bug #21144] Win32: Convert the time zone name to the current locale
The Windows time zone IDs provided by Microsoft as of 24H1 are ASCII
only all, but the API itself is not impossible to set non-ASCII key
name. Prefer the current locale encoding for now until we move to
UTF-8 including environment variables and command line arguments.

YJIT: Filter `&` calls from specialized C method codegen
Evident with the crash reported in [Bug #20997], the C replacement
codegen functions aren't authored to handle block arguments (nor
should they because the extra code from the complexity defeats
optimization). Filter sites with VM_CALL_ARGS_BLOCKARG.

Crash when malloc during GC
This feature was introduced in commit 2ccf6e5, but I realized that
using rb_warn is a bad idea because it allocates objects, which causes
a different crash ("object allocation during garbage collection phase").
We should just hard crash here instead.

[Bug #20915] Fix SEGV with `TracePoint#parameters` and aliased C method
The following snippet results with a SEGV:
```ruby
C = Class.new do
alias_method :new_to_s, :to_s
end
TracePoint.new(:c_call, &:parameters).enable { C.new.new_to_s }
```
at MRI 3.3.6 and ruby 3.4.0dev
The root cause of the issue lies in the `rb_tracearg_parameters` function
within the `RUBY_EVENT_C_RETURN` branch. Specifically, when the invoked
method is an alias for a C function,
`rb_method_entry_without_refinements(..., trace_arg->called_id, ...)`
may return NULL. In that case we can fallback to `trace_arg->id`.

Fix use-after-free in constant cache
[Bug #20921]
When we create a cache entry for a constant, the following sequence of
events could happen:
- vm_track_constant_cache is called to insert a constant cache.
- In vm_track_constant_cache, we first look up the ST table for the ID
of the constant. Assume the ST table exists because another iseq also
holds a cache entry for this ID.
- We then insert into this ST table with the iseq_inline_constant_cache.
- However, while inserting into this ST table, it allocates memory, which
could trigger a GC. Assume that it does trigger a GC.
- The GC frees the one and only other iseq that holds a cache entry for
this ID.
- In remove_from_constant_cache, it will appear that the ST table is now
empty because there are no more iseq with cache entries for this ID, so
we free the ST table.
- We complete GC and continue our st_insert. However, this ST table has
been freed so we now have a use-after-free.
This issue is very hard to reproduce, because it requires that the GC runs
at a very specific time. However, we can make it show up by applying this
patch which runs GC right before the st_insert to mimic the st_insert
triggering a GC:
diff --git a/vm_insnhelper.c b/vm_insnhelper.c
index 3cb23f06f0..a93998136a 100644
--- a/vm_insnhelper.c
+++ b/vm_insnhelper.c
@@ -6338,6 +6338,10 @@ vm_track_constant_cache(ID id, void *ic)
rb_id_table_insert(const_cache, id, (VALUE)ics);
}
+ if (id == rb_intern("MyConstant")) rb_gc();
+
st_insert(ics, (st_data_t) ic, (st_data_t) Qtrue);
}
And if we run this script:
Object.const_set("MyConstant", "Hello!")
my_proc = eval("-> { MyConstant }")
my_proc.call
my_proc = eval("-> { MyConstant }")
my_proc.call
We can see that ASAN outputs a use-after-free error:

This commit fixes this bug by adding a inserting_constant_cache_id field
to the VM, which stores the ID that is currently being inserted and, in
remove_from_constant_cache, we don't free the ST table for ID equal to
this one.

[win32/registry] Fallback to UTF-8 for unknown codepages
There are some codepages like cp708 for which no ruby encoding exists:
$ ruby -e "Encoding.find('cp708')"
Traceback (most recent call last):
1: from -e:1:in `<main>'
-e:1:in `find': unknown encoding name - cp708 (ArgumentError)
win32/registry uses ENCODING to transcode error messages and expand environment
variables from UTF-16LE, so using UTF-8 seems like the best choice and is better
than a hard failure.
