Remove no-op GiST support functions in the core GiST opclasses.
The preceding patch allowed us to remove useless GiST support functions.
This patch actually does that for all the no-op cases in the core GiST
code. This buys us whatever performance gain is to be had, and more
importantly exercises the preceding patch.
There remain no-op functions in the contrib GiST opclasses, but those
will take more work to remove.
