/// Alloca is not only value which can escape. Call e.g. may create
/// a value without Alloca
/// define dso_local ptr @gep_func() {
// entry : % p = alloca ptr, align 8 % pGEP = getelementptr inbounds i8, ptr % p,
// i64 24 % LoadedGEP = load i64, ptr % pGEP,
// align 8 % call = call ptr @func() % data = getelementptr inbounds i8,
// ptr % call, i64 48 store i64 % LoadedGEP, ptr % data,
// align 8 ret ptr % call
// }
