John Naylor c9bfa40914 Split out tiebreaker comparisons from comparetup_* functions ...

Previously, if a specialized comparator found equal datum1 keys,
the "comparetup" function would repeat the comparison on the
datum before proceeding with the unabbreviated first key
and/or additional sort keys.

Move comparing additional sort keys into "tiebreak" functions so
that specialized comparators can call these directly if needed,
avoiding duplicate work.
