Log:
        PR c++/87357 - missing -Wconversion warning
        * decl.c (grok_op_properties): Remove diagnostic parts mentioning
        a conversion to a reference to void.  Use
        same_type_ignoring_top_level_qualifiers_p rather than comparing types
        directly.

        * g++.dg/warn/Wconversion5.C: New test.
