Closes #20532. This implements CLC proposal 104:
https://github.com/haskell/core-libraries-committee/issues/104
The design is explained in Note [DataToTag overview]
in GHC.Tc.Instance.Class. This replaces the existing
`dataToTag#` primop.
These metric changes are not "real"; they represent Unique-related
flukes triggering on a different set of jobs than they did previously.
See also #19414.
