Is this correct? I get that the `cmp` is somewhat ill-formed (`false`), but I
don't see how this ever reduces to an `%x == null` check with a non-zero offset.
Also seems to also apply `address_is_null` w.o `inbounds`:
```
define i1 @nocaptureInboundsGEPICmp(ptr %x, i64 %y) {
%1 = getelementptr i8, ptr %x, i64 %y
%2 = icmp eq ptr %1, null
ret i1 %2
}
```
=>
```
define i1 @nocaptureInboundsGEPICmp(ptr readnone captures(address_is_null) %x,
i64 %y) {
%1 = getelementptr i8, ptr %x, i64 %y
%2 = icmp eq ptr %1, null
ret i1 %2
}
```
How is that correct?
