Fix for luanchpad bug#609043

Removed indirect reference in equalities for cache index lookup.

We should use a direct reference because some optimization of the
query may optimize out a condition predicate and if the outer reference
is the only element of the condition predicate the indirect reference
becomes NULL.

We can resolve correctly the indirect reference in
Expression_cache_tmptable::make_equalities because it is called before
optimization of the cached subquery.

Bugfix for lounchpad bug#608834 (608824, 609045, 609052).

Added get_tmp_table_item() to cache wrapper as it has all not simple Items (Item_func, Item_field, Item_subquery).

2805. By Timour Katchaounov on 2010-07-16

Fixed a problem where the temp table of a materialized subquery
was not cleaned up between PS re-executions. The reason was two-fold:
- a merge with mysql-6.0 missed select_union::cleanup() that should
  have cleaned up the temp table, and
- the subclass of select_union used by materialization didn't call
  the base class cleanup() method.

range plans with identical costs.

2801. By Timour Katchaounov on 2010-07-15

Fixed an error in the creation of REF access method for materialized
subquery execution, where the the REF buffer format was mistaken to
be in record format instead of key format. The error was that the null
byte for all fields of the record was in the front of the buffer,
and not before each field data.

2800. By Oleksandr "Sanja" Byelkin on 2010-07-10

Subquery cache (MWL#66) added.
