// If node `A` depends on node `B` then the path contains an `A`->`B` edge.
// From the call stack of the import functions we can read the very same
// path.
//
// Now imagine the following AST, where the `->` represents dependency in
// therms of the import.
// ```
// A->B->C->D
// `->E
// ```
// We would like to import A.
// The import behaves like a DFS, so we will visit the nodes in this order:
// ABCDE.
// During the visitation we will have the following ImportPaths:
// ```
// A
// AB
// ABC
// ABCD
// ABC
// AB
// ABE
// AB
// A
// ```
// If during the visit of E there is an error then we set an error for E,
// then as the call stack shrinks for B, then for A:
// ```
// A
// AB
// ABC
// ABCD
// ABC
// AB
// ABE // Error! Set an error to E
// AB // Set an error to B
// A // Set an error to A
// ```
// However, during the import we could import C and D without any error and
// they are independent from A,B and E.
// We must not set up an error for C and D.
// So, at the end of the import we have an entry in `ImportDeclErrors` for
// A,B,E but not for C,D.
//
// Now what happens if there is a cycle in the import path?
// Let's consider this AST:
// ```
// A->B->C->A
// `->E
// ```
// During the visitation we will have the below ImportPaths and if during
// the visit of E there is an error then we will set up an error for E,B,A.
// But what's up with C?
// ```
// A
// AB
// ABC
// ABCA
// ABC
// AB
// ABE // Error! Set an error to E
// AB // Set an error to B
// A // Set an error to A
// ```
// This time we know that both B and C are dependent on A.
// This means we must set up an error for C too.
// As the call stack reverses back we get to A and we must set up an error
// to all nodes which depend on A (this includes C).
// But C is no longer on the import path, it just had been previously.
// Such situation can happen only if during the visitation we had a cycle.
// If we didn't have any cycle, then the normal way of passing an Error
// object through the call stack could handle the situation.
// This is why we must track cycles during the import process for each
// visited declaration.

/// multiple, virtual inheritance, it is possible for a class to have
/// more than one final overrider. Although this is an error (per C++
/// [class.virtual]p2), it is not considered an error here: the final
/// overrider map can represent multiple final overriders for a
/// method, and it is up to the client to determine whether they are
/// problem. For example, the following class \c D has two final
/// overriders for the virtual function \c A::f(), one in \c C and one
/// in \c D:
///
/// \code
/// struct A { virtual void f(); };
/// struct B : virtual A { virtual void f(); };
/// struct C : virtual A { virtual void f(); };
/// struct D : B, C { };
/// \endcode
///
/// This data structure contains a mapping from every virtual
/// function *that does not override an existing virtual function* and
/// in every subobject where that virtual function occurs to the set
/// of virtual functions that override it. Thus, the same virtual
/// function \c A::f can actually occur in multiple subobjects of type
/// \c A due to multiple inheritance, and may be overridden by
/// different virtual functions in each, as in the following example:
///
/// \code
/// struct A { virtual void f(); };
/// struct B : A { virtual void f(); };
/// struct C : A { virtual void f(); };
/// struct D : B, C { };
/// \endcode
///
/// Unlike in the previous example, where the virtual functions \c
/// B::f and \c C::f both overrode \c A::f in the same subobject of
/// type \c A, in this example the two virtual functions both override
/// \c A::f but in *different* subobjects of type A. This is
