This patch changes MemoryAccessKind to a class wrapping the existing
enum. This allows adding additional information that's independent of
the existing values, like argmemonly.

ArgMemOnly support will be added in D121415 <https://reviews.llvm.org/D121415>.

This might be a bit heavy-handed, as an alternative checkFunctionMemoryAccess
could return a pair or a struct with fields for MemoryAccessKind and
ArgMemOnly. I don't have any strong preferences.
