A vestigial remnant of it was left behind after
06921cfe84 in order to avoid a reverse
condfail when building old swiftinterfaces that define
```swift
func _copy<T>(_ value: T) -> T {
#if $BuiltinCopy
Builtin.copy(value)
#else
value
#endif
}
```
If the language feature is removed, though, such interfaces should again
be buildable because the branch where the language feature isn't defined
should be expanded.
