Hmm..looks like moving it to CodeGenTarget is causing problems with SearchableTableEmitter. Even though it instantiates it only if needed, there seems to be cases  like AMDGPU/InstCombineTables.td where it fails because it only includes Intrinsics.id but not Target.td. I'll look if there are just a few of these cases (and its ok to change the include to be Target.td there as it includes Intrinsics.td) or do something else.
