Perhaps we *could* address this in libiberty: have a macro that
converts a pointer type to a value that can be passed to the hash
function that doesn't trigger warnings and tries not to lose
significant bits.  Then adjust GCC to use such a macro whenever it
wants to pass a pointer to the function that computes a hash.
