Change the test from using the old x_diff method to the new direct diff method for checking that the results don't differ in the optimized and unoptimized cases. This cleans up the golden file so that in case of success the golden files are nearly empty instead of containing a diff file that must be checked to ensure that it only has explain (and not tuple) output. Also combine several test files into query.sql, and get rid of differences in pg versions.
