merge revision(s) 3592b24cdc07ed89eecb39161f21fe721a89a5de: [Backport #19531]
ObjectSpace::WeakMap: clean inverse reference when an entry is
re-assigned
[Bug #19531]
```ruby
wmap[1] = "A"
wmap[1] = "B"
```
In the example above, we need to remove the `"A" => 1` inverse reference
so that when `"A"` is GCed the `1` key isn't deleted.
