  -----------
  Reapply "[Attributor] Disable simplification AAs if a callback is present""

This reapplies commit cbb709e25124dc38ee593882051fc88c987fe591 and
includes the use of the lookup method instead of operator[] to avoid
accidentally setting (empty) simplification callbacks.

This reverts commit aa27430a625b2fd059707a87f8ba2df8f480ff11.
