Skip unnecessary get_relids_in_jointree() when there are no PHVs

Commit 1df9e8d96 made remove_useless_result_rtes() compute the set of
baserels in the jointree, to pass down to the find_dependent_phvs()
checks.  But those checks are no-ops when the query contains no PHVs,
since find_dependent_phvs() and find_dependent_phvs_in_jointree() both
return early in that case.  So we can avoid the
get_relids_in_jointree() scan altogether when root->glob->lastPHId is
zero, leaving baserels as NULL.
