[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("-&gt; { MyConstant }")
    my_proc.call

    my_proc = eval("-&gt; { 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.

* Add opt_duparray_send insn to skip the allocation on `#include?`

If the method isn't going to modify the array we don't need to copy it.
This avoids the allocation / array copy for things like `[:a, :b].include?(x)`.

This adds a BOP for include? and tracks redefinition for it on Array.

Many libraries should be loaded on the main ractor because of
setting constants with unshareable objects and so on.

This patch allows to call `requore` on non-main Ractors by
asking the main ractor to call `require` on it. The calling ractor
waits for the result of `require` from the main ractor.

If the `require` call failed with some reasons, an exception
objects will be deliverred from the main ractor to the calling ractor
if it is copy-able.

Same on `require_relative` and `require` by `autoload`.

Now `Ractor.new{pp obj}` works well (the first call of `pp` requires
`pp` library implicitly).

to show unused block warning strictly.

```ruby
class C
  def f = nil
end

class D
  def f = yield
end

[C.new, D.new].each{|obj| obj.f{}}
```

In this case, `D#f` accepts a block. However `C#f` doesn't
accept a block. There are some cases passing a block with
`obj.f{}` where `obj` is `C` or `D`. To avoid warnings on
such cases, "unused block warning" will be warned only if
there is not same name which accepts a block.
On the above example, `C.new.f{}` doesn't show any warnings
because there is a same name `D#f` which accepts a block.

We call this default behavior as "relax mode".

`strict_unused_block` new warning category changes from
"relax mode" to "strict mode", we don't check same name
methods and `C.new.f{}` will be warned.
