571e14f897 More performance improvements to metadata lazyloading.
Comment and term meta lazyloading for `WP_Query` loops, introduced in 4.4,
depended on filter callback methods belonging to `WP_Query` objects. This meant
storing `WP_Query` objects in the `$wp_filter` global (via `add_filter()`),
requiring that PHP retain the objects in memory, even when the local variables
would typically be expunged during normal garbage collection. In cases where a
large number of `WP_Query` objects were instantiated on a single pageload,
and/or where the contents of the `WP_Query` objects were quite large, serious
performance issues could result.

We skirt this problem by moving metadata lazyloading out of `WP_Query`. The
new `WP_Metadata_Lazyloader` class acts as a lazyload queue. Query instances
register items whose metadata should be lazyloaded - such as post terms, or
comments - and a `WP_Metadata_Lazyloader` method will intercept comment and
term meta requests to perform the cache priming. Since `WP_Metadata_Lazyloader`
instances are far smaller than `WP_Query` (containing only object IDs), and
clean up after themselves far better than the previous `WP_Query` methods (bp
only running their callbacks a single time for a given set of queued objects),
the resource use is decreased dramatically.

See [36525] for an earlier step in this direction.

3e9c88d75a In delete_metadata(), only invalidate cache for affected objects.
The `$delete_all` flag in `delete_metadata()` triggers cache invalidation for
multiple objects. Previously, invalidation took place for all objects matching
the `$meta_key` parameter, regardless of whether `$meta_value` was also set.
This resulted in overly aggressive invalidation.

5dfd6a02a7 Avoid returning duplicate matches when using a meta query in WP_User_Query.
A meta_query containing an `OR` relation can result in the same record matching
multiple clauses, leading to duplicate results. The previous prevention against
duplicates [18178] #17582 became unreliable in 4.1 when `WP_Meta_Query`
introduced support for nested clauses. The current changeset adds a new method
`WP_Meta_Query::has_or_relation()` for checking whether an `OR` relation
appears anywhere in the query, and uses the new method in `WP_User_Query` to
enforce distinct results as necessary.

ca30c725a0 Improve support for ordering WP_Query results by postmeta.
`WP_Meta_Query` clauses now support a 'name' parameter. When building a
`WP_Query` object, the value of 'orderby' can reference this 'name', so that
it's possible to order by any clause in a meta_query, not just the first one
(as when using 'orderby=meta_value'). This improvement also makes it possible
to order by multiple meta query clauses (or by any other eligible field plus
a meta query clause), using the array syntax for 'orderby' introduced in [29027].

9345e9ffa5 Overhaul SQL generating logic in WP_Meta_Query to avoid unnecessary table joins.
The logic used to generate clause SQL in `WP_Meta_Query` is somewhat arcane,
stemming mostly from an ongoing effort to eliminate costly table joins when
they are not necessary. By systematizing the process of looking for shareable
joins - as was done in `WP_Tax_Query` [29902] - it becomes possible to simplify
the construction of SQL queries in `get_sql_for_clause()`. Moreover, the
simplified logic is actually considerably better at identifying shareable
joins, such that certain uses of `WP_Meta_Query` will see joins reduced by 50%
or more.

Includes integration tests for a representative cross-section of the query
clause combinations that result in shared table aliases.
