expr.c (emit_move_via_integer): Add force argument, pass it on to emit_move_change_mode. 

* expr.c (emit_move_via_integer): Add force argument, pass it on
        to emit_move_change_mode.  Update callers.
        (emit_move_complex): Pass true to new force argument.
        * function.c (expand_function_end): Move expand_eh_return call
        earlier.  Merge sub-word complex values into a pseudo before
        copying to the return hard register.
