  AMDGPU: Restrict attributor transforms

We only really want this to add the custom attributes. Theoretically
the regular transforms were already run at this point. Touching
undefined behavior breaks a lot of tests when this is enabled by
default, many of which are expecting to test handling of undef
operations.
