Turns out this fix is incomplete. This code is still broken:

class B
{
}

class A : B
{
    alias set opAssign;

    void set(B a)
    {
    }
}

and it throws an ICE:

dmd: clone.c:35: FuncDeclaration*
AggregateDeclaration::hasIdentityOpAssign(Scope*, Dsymbol*): Assertion
`assign->ident == Id::assign' failed.

This is actually the closer to the original code that had the bug... shows me
right to try to reduce the code... I get a reduced fix!
