You might be able to just do this (we don't use anything from the APSInt at all
so we can tweak the callback to take APInt refs):
```
return interp__builtin_elementwise_int_binop(
S, OpPC, Call, [](const APInt &AElem, const APInt &BElem) {
if (BElem.isZero())
return APInt::getZero(AElem.getBitWidth());
if (BElem.isNegative())
return -AElem;
return AElem;
});
```
