----------------
Add checks/check-nots to make sure the thing you don't want isn't emitted, not just `!nosanitize`
The checks help document what you're trying to get in each test case.
Here I'd prefer to have a `CHECK-NOT: __ubsan_handle_load_invalid_value` than a check-not for `!nosanitize`, since checking for the handler call is more explicit.
