// The argument and parameter types can be different for legitimate

// example where this happens is when inlining shared code into a
// non-generic function, in which case we might see the __Canon in
// the parameter type but exact types in the signature type.

// TODO-ARGS: Remove this quirk; we should be able to use the
// signature type that is different in the rare case above. It will
// cause positive diffs, but that is probably an indication that we
// have downstream phases that should be using
// `ClassLayout::AreCompatible` instead.
