for overriding conditions. That is for overriding member M and overridden member O:

- Check all members of class
clazz
for overriding conditions. That is for overriding member M and overridden member O:
1.1. M must have the same or stronger access privileges as O.
1.2. O must not be final.
1.3. O is deferred, or M has override
modifier.
1.4. If O is stable, then so is M.
// @M: LIFTED 1.5. Neither M nor O are a parameterized type alias
1.6. If O is a type alias, then M is an alias of O.
1.7. If O is an abstract type then
1.7.1 either M is an abstract type, and M's bounds are sharper than O's bounds.
or M is a type alias or class which conforms to O's bounds.
1.7.2 higher-order type arguments must respect bounds on higher-order type parameters -- @M
(explicit bounds and those implied by variance annotations) -- @see checkKindBounds
1.8. If O and M are values, then
1.8.1 M's type is a subtype of O's type, or
1.8.2 M is of type []S, O is of type ()T and S <: T, or
1.8.3 M is of type ()S, O is of type []T and S <: T, or
1.9. If M is a macro def, O cannot be deferred unless there's a concrete method overriding O.
1.10. If M is not a macro def, O cannot be a macro def.
2. Check that only abstract classes have deferred members
3. Check that concrete classes do not have deferred definitions
that are not implemented in a subclass.
4. Check that every member with an override
modifier
overrides some other member.
TODO check that classes are not overridden
TODO This still needs to be cleaned up; the current version is a staright port of what was there
before, but it looks too complicated and method bodies are far too large.
Check that a class and its companion object to not both define a class or module with same name

Check that a deprecated val or def does not override a concrete, non-deprecated method. If it does, then deprecation is meaningless.
