[IR] Remove support for lshr/ashr constant expressions (#71955)

Remove support for the lshr and ashr constant expressions. All places
creating them have been removed beforehand, so this just removes the
APIs and uses of these constant expressions in tests.

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