Enable methods to sort map keys and spew itself as last resort
If enabled by flags, try to use methods to stringify map keys and sort on that.
If we can't use primitive sorting and we can't use methods, we can still fall
back on spew itself. If SpewKeys is enabled, use Sprintf("%#v") to generate a
string and sort by that.
