Erik Eckstein 6ff3b91fe4 SimplifyDestructure: support simplifying a destructure_struct with a copy_value in place ...

Replace
```
  %s = struct (%0, %1, %2)
  %c = copy_value %s           // can also be a chain of multiple copies
  (%3, %4, %5) = destructure_struct %c
```
with
```
  %c0 = copy_value %0
  %c1 = copy_value %1
  %c2 = copy_value %2
  %s = struct (%0, %1, %2)    // keep the original struct
```
and replace the results %3, %4, %5 with %c0, %c1, %c2, respectively.
