…ith a `store`
For example:
```
%0 = load %1
copy_addr %1 to %2
```
->
```
%0 = load %1
store %0 to %2
```
This is important for MandatoryRedundantLoadElimination to be able to create statically initialized globals in the mandatory pipeline.
For example:
```
public struct MyStruct {
public static let r: Range<Int> = 1 ..< 3
}
```
gets a statically initialized global, even at Onone, with this improvement.
