Working on the tests for new SP-GiST opclasses for polygons and circles, I've
found a bug in the SP-GiST box_ops (added in 9.6): some operators
(&<, &>, $<|, |&>) have wrong tests in spg_box_quad_inner_consistent().
This obviously leads to incorrect results of a SP-GiST index scan (see tests
in the attached patch, their results were taken from a sequential scan).
