3556a834a2847e52162d1d3302d4c64390df1694 added support for
Module#include to affect the iclasses of the module. It didn't add
support for Module#prepend because there were bugs in the object model
and GC at the time that prevented it. Those problems have been
addressed in ad729a1d11c6c57efd2e92803b4e937db0f75252 and
98286e9850936e27e8ae5e4f20858cc9c13d2dde, and now adding support for
it is straightforward and does not break any tests or specs.
Fixes [Bug #9573]

This fixes various issues when a module is included in or prepended
to a module or class, and then refined, or refined and then included
or prepended to a module or class.
Implement by renaming ensure_origin to rb_ensure_origin, making it
non-static, and calling it when refining a module.
Fix Module#initialize_copy to handle origins correctly. Previously,
Module#initialize_copy did not handle origins correctly. For example,
this code:
```ruby
module B; end
class A
def b; 2 end
prepend B
end
a = A.dup.new
class A
def b; 1 end
end
p a.b
```
Printed 1 instead of 2. This is because the super chain for
a.singleton_class was:
```
a.singleton_class
A.dup
B(iclass)
B(iclass origin)
A(origin) # not A.dup(origin)
```
The B iclasses would not be modified, so the includer entry would be
still be set to A and not A.dup.
This modifies things so that if the class/module has an origin,
all iclasses between the class/module and the origin are duplicated
and have the correct includer entry set, and the correct origin
is created.
This requires other changes to make sure all tests still pass:
* rb_undef_methods_from doesn't automatically handle classes with
origins, so pass it the origin for Comparable when undefing
methods in Complex. This fixed a failure in the Complex tests.
* When adding a method, the method cache was not cleared
correctly if klass has an origin. Clear the method cache for
the klass before switching to the origin of klass. This fixed
failures in the autoload tests related to overridding require,
without breaking the optimization tests. Also clear the method
cache for both the module and origin when removing a method.
* Module#include? is fixed to skip origin iclasses.
* Refinements are fixed to use the origin class of the module that
has an origin.
* RCLASS_REFINED_BY_ANY is removed as it was only used in a single
place and is no longer needed.
* Marshal#dump is fixed to skip iclass origins.
* rb_method_entry_make is fixed to handled overridden optimized
methods for modules that have origins.

If a module has an origin, and that module is included in another
module or class, previously the iclass created for the module had
an origin pointer to the module's origin instead of the iclass's
origin.
Setting the origin pointer correctly requires using a stack, since
the origin iclass is not created until after the iclass itself.
Use a hidden ruby array to implement that stack.
Correctly assigning the origin pointers in the iclass caused a
use-after-free in GC. If a module with an origin is included
in a class, the iclass shares a method table with the module
and the iclass origin shares a method table with module origin.
Mark iclass origin with a flag that notes that even though the
iclass is an origin, it shares a method table, so the method table
should not be garbage collected. The shared method table will be
garbage collected when the module origin is garbage collected.
I've tested that this does not introduce a memory leak.
This change caused a VM assertion failure, which was traced to callable
method entries using the incorrect defined_class. Update
rb_vm_check_redefinition_opt_method and find_defined_class_by_owner
to treat iclass origins different than class origins to avoid this
issue.
This also includes a fix for Module#included_modules to skip
iclasses with origins.

Some tests need to setup Other class with OtherSetup proc.
|

When calling Module#include, if the receiver is a module,
walk the subclasses list and include the argument module in each
iclass.
This does not affect Module#prepend, as fixing that is significantly
more involved.

This makes it possible to initialize_clone to correctly not freeze
internal state if the freeze: false keyword is passed to clone.
If clone is called with freeze: true or no keyword, do not pass
a second argument to initialize_clone to keep backwards
compatibility.
This makes it so that external libraries that override
initialize_clone but do not support the freeze keyword will fail
with ArgumentError if passing freeze: false to clone. I think that
is better than the current behavior, which succeeds but results in
an unfrozen object with frozen internals.
Fix related issues in set and delegate in stdlib.

This makes it consistent with calling private attribute assignment
methods, which currently is allowed (e.g. `self.value =`).
Calling a private method in this way can be useful when trying to
assign the return value to a local variable with the same name.

b00f280d4b9569e7153365d7e1c522b3d6b3c6cf introduced
an accidental behavior change in that defining a module/class under
`m` gives `m` a name when `m` is anonymous.
`ruby -ve 'Module.new { class self::A; end; p name }'` outputs a name
similar to `Module#inspect` when it should output `nil` like in Ruby
2.6.x.

Methods on duplicated class/module refer same constant inline
cache (IC). Constant access lookup should be done for cloned
class/modules but inline cache doesn't check it.
To check it, this patch introduce new RCLASS_CLONED flag which
are set when if class/module is cloned (both orig and dst).

receiver
Previously, attr* methods could be private even if not in the
private section of a class/module block.
This uses the same approach that ruby started using for define_method

Module has many introspection methods for methods and constants that
either return an array or return true or false for whether the method
or constant is defined. Most of these methods support an optional
argument that controls whether to consider inheritance. Currently,
the following Module methods support such a argument:
* const_defined?
* constants
* instance_methods
* private_instance_methods
* protected_instance_methods
* public_instance_methods
and the following methods do not:
* method_defined?
* private_method_defined?
* protected_method_defined?
* public_method_defined?
This patch supports such an argument for the *method_defined?
methods.
While you can currently work around the lack of support via:
mod.instance_methods(false).include?(:method_name)
This patch allows the simpler and more efficient:
mod.method_defined?(:method_name, false)
One case where you want to exclude inheritance when checking
for a method definition is when you want to replace a method
that may already exist. To avoid a verbose warning, you want
to remove the method only if it is already defined:
remove_method(:foo) if method_defined?(:foo, false)
define_method(:foo){}
You can't call remove_method without checking for the method
definition, as that can raise a NameError, and you don't want
to include inheritance because remove_method will still raise
a NameError if the method is defined by an ancestor and not
by the module itself.

FrozenError will be used instead of RuntimeError for exceptions
raised when there is an attempt to modify a frozen object. The
