iter_lev is used to detect the hash is iterating or not.
Usually, iter_lev should be very small number (1 or 2) so
`int` is overkill.
This patch introduce iter_lev in flags (7 bits, FL13 to FL19)
and if iter_lev exceeds this range, save it in hidden attribute.
We can get 1 word in RHash.
We can't modify frozen objects. Therefore I added new internal API
`rb_ivar_set_internal()` which allows us to set an attribute
even if the target object is frozen
if the name is hidden ivar (the name without `@` prefix).
* variable.c: make the hidden ivars `classpath` and `tmp_classpath` the source
of truth for module and constant names. Assign to them when modules are bind
to constants.
* variable.c: remove references to module name cache, as what used to be the cache
is now the source of truth. Remove rb_class_path_no_cache().
* variable.c: remove the hidden ivar `classid`. This existed for the purposes of
module name search, which is now replaced. Also, remove the associated
rb_name_class().
* class.c: use rb_set_class_path_string to set the name of Object during boot.
Must use a fstring as this runs before rb_cString is initialized and
creating a normal string leads to a VALUE without a class.
* spec/ruby/core/module/name_spec.rb: add a few specs to specify what happens
to Module#name across multiple operations. These specs pass without other
code changes in this commit.
[Feature #15765]
autoload_reset() can read this state.result. Because autoload_reset
is a function passed to rb_ensure, there is a chance when an
execption raises before actually filling this memory region.
test/ruby/test_defined.rb:test_autoload_noload is one of such case.
Found using memory sanitizer.

An instruction is leaf if it has no rb_funcall inside. In order to
check this property, we introduce stack canary which is a random
number collected at runtime. Stack top is always filled with this
number and checked for stack smashing operations, when VM_CHECK_MODE.

Just refactoring. Despite its name, the function does NOT return a
boolean but raises an exception when the class given is frozen.
I don't think the new name "rb_class_modify_check" is the best, but
it follows the precedeint "rb_ary_modify_check", and is definitely
better than "*_p".

We need to ensure autoload declarations pointing to the same
feature (aka "file") can wait on each other to avoid deadlock
situations.
So, reorganize autoload data structures to maintain a
feature => autoload_data_i mapping, and have module constant
tables point to the new autoload_const struct instead of
directly to autoload_data_i. This allows multiple
autoload_const structs to refer to the SAME autoload_data_i
struct, and with it, the on-stack autoload_state.waitq.
The end result is different constants can share the same waitq
(tied to the feature name), and not deadlock each other during
loading.
Thanks to Eugene Kenny for the bug report and reproducible test case.
