                ST.hasVInstructionsI64()) &&
               (Query.Types[0].getElementCount().getKnownMinValue() != 1 ||
                ST.getELen() == 64);
      })
```

typeInSet will copy the initialize_list to a SmallVector before creating a lambda. I think by calling it as part of `all` that lambda will get created before the initializer list goes out of scope.
