RFR(xs): 8149096: Remove unused code in methodComparator

[Thomas Stüfe]

Hi all,

please review and sponsor this little change. It gets rid of two unused
methods in methodComparator(cpp/hpp).

We stumbled over this because of warings about unchecked realloc() return
values; but instead of fixing the code, we may just remove the offending
methods, because they are not used anywhere.
