Compile the following with -fwrapv-pointer:
```
struct S { int x,y; };
int *a(struct S *x) { return &x->y; }
```
Produces `getelementptr inbounds nuw %struct.S, ptr %0, i32 0, i32 1`... which seems counter to the premise of -fwrapv-pointer. And seems like it might be a problem with https://github.com/llvm/llvm-project/pull/130742 .
