Back-patch "Fix parallel hash join path search."
Back-patch commit 655393a022bd653e2b48dbf20b69236981e35195 to 9.6. This
synchronizes the relavant code and helps in generating parallel paths in
some cases in 9.6. This also helps in back-patch of future patches where
we can get the same plan in all branches.
