Nikita Popov e4a4122eb6 [IR] Remove zext and sext constant expressions (#71040)
Remove support for zext and sext constant expressions. All places
creating them have been removed beforehand, so this just removes the
APIs and uses of these constant expressions in tests.

There is some additional cleanup that can be done on top of this, e.g.
we can remove the ZExtInst vs ZExtOperator footgun.

This is part of
https://discourse.llvm.org/t/rfc-remove-most-constant-expressions/63179.
