Boone Gorges 56c82e534f Avoid redundant table joins in WP_Tax_Query. ... IN clauses that are connected by OR require only a single table join. To avoid extraneous joins, keep track of generated table aliases, and let sibling clauses piggy-back on those aliases when possible. Introduces WP_Tax_Query::sanitize_relation() to reduce some repeated code. Adds unit tests to verify the JOIN consolidation, and integration tests for cases where JOINS are being combined. Props boonebgorges, otto42, jakub.tyrcha. Fixes #18105. git-svn-id: https://develop.svn.wordpress.org/trunk@29902 602fd350-edb4-49c9-b593-d223f7449a82		2014-10-15 16:39:19 +00:00
