PmCheck: Identify some semantically equivalent expressions
By introducing a `CoreMap Id` to the term oracle, we can represent
syntactically equivalent expressions by the same `Id`. Combine that with
`CoreOpt.simpleCoreExpr` and it might even catch non-trivial semantic
equalities.
Unfortunately due to scoping issues, this will not solve #17208 for
view patterns yet.
