[PATCH] D93850: [InstCombine] Rewrite (switch (zext X)) as (switch X).

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

Aha, i see. I think the existing fold should be fixed instead,
because if it doesn't fire (because `shouldChangeType()` said so?),
how do we know we can ignore that hook here?
