Right now the attached object is stored as an instance variable
and all the call sites that either get or set it have to know how it's
stored.
It's preferable to hide this implementation detail behind accessors
so that it is easier to change how it's stored.
This patch is follo-up of 0a82bfe.
Without this patch, if env is escaped (Proc'ed), strange svar
can be touched.
This patch tracks escaped env and use it.
* use correct svar
Without this patch, svar location is used "nearest Ruby frame".
It is almost correct but it doesn't correct when the `each` method
is written in Ruby.
```ruby
class C
include Enumerable
def each
%w(bar baz).each{|e| yield e}
end
end
C.new.grep(/(b.)/){|e| p [$1, e]}
```
This patch fix this issue by traversing ifunc's cfp.
Note that if cfp doesn't specify this Thread's cfp stack, reserved
svar location (`ec->root_svar`) is used.

UnboundMethod records caller's class, like `D` or `E` on the
following case:
```ruby
class C
def foo = :foo
end
class D < C
end
class E < C
end
d = D.instance_method(:foo)
e = E.instance_method(:foo)
```
But `d` and `e` only refers `C#foo` so that UnboundMethod doesn't
record `D` or `E`. This behavior changes the following methods:
* `UnboundMethod#inspect` (doesn't show caller's class)
* `UnboundMethod#==` (`d == e` for example)

Based on c95e7e5329
Among other things, this fixes calling visibility methods (public?,
protected?, and private?) on them. It also fixes #owner to show the
class the zsuper method entry is defined in, instead of the original
class it references.
For some backwards compatibility, adjust #parameters and #source_location,
to show the parameters and source location of the method originally
defined. Also have the parameters and source location still be shown
by #inspect.
Clarify documentation of {Method,UnboundMethod}#owner.
Add tests based on the description of https://bugs.ruby-lang.org/issues/18435
and based on https://github.com/ruby/ruby/pull/5356#issuecomment-1005298809

I noticed that this site unconditionally clones the method entry, which
means that `bind_call` always allocates a `T_IMEMO`. While this clone
is necessary for `bind`, it is not necessary for `bind_call`.
I work at Stripe, and the sorbet_runtime gem uses bind call as part
of it's [call validation](https://github.com/sorbet/sorbet/blob/master/gems/sorbet-runtime/lib/types/private/methods/call_validation.rb#L157)
so this can save us a lot of allocations.
This patch adds a `clone` parameter to `convert_umethod_to_method_components`,
which then controls whether or not we do this cloning. This patch passed
Stripe CI and works in our QA environment. I reviewed it with @tenderlove
to talk about correctness also.
This reverts commit 2727815068 and
58dc8bf8f1.
Visibility is an attribute of the method entry in a class, not an
attribute of the Method object.

Fixes [#18435]
rb_ary_tmp_new suggests that the array is temporary in some way, but
that's not true, it just creates an array that's hidden and not on the
transient heap. This commit renames it to rb_ary_hidden_new.
Use ISEQ_BODY macro to get the rb_iseq_constant_body of the ISeq. Using
this macro will make it easier for us to change the allocation strategy
of rb_iseq_constant_body when using Variable Width Allocation.
Add a visibility member to struct METHOD storing the original
method visibility, and use that, instead of taking the visibility
from the stored method entry (which may have different visibility
for ZSUPER methods).
Consider Method/UnboundMethod objects different if they have
different visibilities.
Fixes [Bug #18435]
This allows for the following syntax:
```ruby
def foo(*)
bar(*)
end
def baz(**)
quux(**)
end
```
This is a natural addition after the introduction of anonymous
block forwarding. Anonymous rest and keyword rest arguments were
already supported in method parameters, this just allows them to
be used as arguments to other methods. The same advantages of
anonymous block forwarding apply to rest and keyword rest argument
forwarding.
This has some minor changes to #parameters output. Now, instead
of `[:rest], [:keyrest]`, you get `[:rest, :*], [:keyrest, :**]`.
These were already used for `...` forwarding, so I think it makes
it more consistent to include them in other cases. If we want to
use `[:rest], [:keyrest]` in both cases, that is also possible.
I don't think the previous behavior of `[:rest], [:keyrest]` in
the non-... case and `[:rest, :*], [:keyrest, :**]` in the ...
case makes sense, but if we did want that behavior, we'll have to
make more substantial changes, such as using a different ID in the
... forwarding case.
