Refactor merge path generation code.
Robert Haas <rhaas@postgresql.org>
Refactor merge path generation code. This shouldn't change the set of paths that get generated in any way, but it is preparatory work for further changes to allow a partial path to be merge-joined witih a non-partial path to produce a partial join path. Dilip Kumar, with cosmetic adjustments by me.
