Two ways that I can think of:
1. Get the typehierarchy (IType->newSupertypeHierarchy() or IType->newTypeHierarchy()) and call the appropriate functions in the hierarchy to see if one is contained in another.
2. Get the bindings using ASTParser->CreateBindings() and call ITypeBinding->isAssignmentCompatible().

Using the ASTParser was the solution i used until now but this is
extremly slow unless I used it inappropriately.

So I'll give solution 1 a try.
