Always allocate CDHASH in 80B slots

Up to size 8, rb_hash_new_with_size() will allocate a 160B
slot to fit a full ar_table.

But in the case of CDHASH, we immediately assign a custom hash
type, which trigger the conversion into an st_table, potentially...

class.c: rb_class_duplicate_classext also dup content of cvc_tbl

[Bug #21952]

Shallow copying the table result in the same memory being shared
between multiple box, causing double free when one of the box
is garbage collected.

ZJIT: Trace infer_types as a sub-pass of other passes (#16714)

This helps us see how much time it takes in compiler tracing.

ZJIT: fmt::Debug for VALUE in hex. Shorthand for rb_obj_info()

The default {:?} still always prints the pointer address and never
dereferences it, but now in hex.

The "alternate" flag lets you do println!("{my_ruby_object:#?}") and
get a rich printout like VALUE(0x000000010232fd00 T_CLASS/Object).

ZJIT: Assert no side exits in assert_compiles()

Most of the time, we want to assert that we compile and the compiled
code runs without exiting. A small number of tests trigger side exits,
and those are changed to use assert_compiles_allowing_exits().

ZJIT: Fix hanging loop (#16711)

https://github.com/ruby/ruby/pull/16122 (c272297e8a9f2b8034739b915707910b4e568479) worked for maximal SSA but
does not work for "normal" SSA. This is because it used information
propagating across block args/params as a proxy for tracking changes in...

Ensure version from bundled_gems is used in tool/rdoc-srcdir (#16712)

Use version from bundled_gems in tool/rdoc-srcdir

Previously, tool/rdoc-srcdir used Dir.glob(...).first to find
bundled gems like rdoc and tsort. This picks the first match
alphabetically, which can select a stale older version when multiple...
