Add GiST and btree sortsupport routines for range types
For GiST, having a sortsupport function allows building the index
using the "sorted build" method, which is much faster.
For b-tree, the sortsupport routine doesn't give any new
functionality, but speeds up sorting a tiny bit. The difference is not
very significant, about 2% in cursory testing on my laptop, because
the range type comparison function has quite a lot of overhead from
detoasting. In any case, since we have the function for GiST anyway,
we might as well register it for the btree opfamily too.
