    d: Fix ICE in in add_stack_var, at cfgexpand.cc:476

    The type that triggers the ICE never got completed by the semantic
    analysis pass.  Checking for size forces it to be done, or issue a
    compile-time error.

    gcc/d/ChangeLog:

            * d-target.cc (Target::isReturnOnStack): Check for return type
