Attributor: Don't follow uses of ConstantData (#134573) 
These should not really have uselists, and it's not worth the compile
time of looking at all uses of trivial constants. The main observable
change of this is it no longer adds align attributes on constant null
uses, but those are not useful. Some of these cases should potentially
be more aggressive and not look at any Constant users.
