In #21031, this can be optimized to reduce the Pointer,usage atomic-operate
for any type, as shown in https://go-review.googlesource.com/c/go/+/617695 .
But we need support for setting atomic values to nil, and we also need a
way to represent deleted values.
The current practice is to make a
encounter that it is always output 1, so I ask.

Does data race in this program affect execution results?
In amd64, it always output1.
```go
package main
import "sync"
func main() {
i := 0
var wg sync.WaitGroup
for range 100 {
wg.Add(1)
go func() {
defer wg.Done()
i = 1
}()
}
wg.Wait()
println(i)
}
```
