[Attributor][NFC] Do not create temporary maps during lookup

The AAMap.lookup() call created a temporary value if the key was not
present. Since the value was another map it was not free to create it.
Instead of a lookup we now use find and compare the result against the
end iterator explicitly. The result is the same but we never need to
create a temporary map.
