unknown ee3b7b56e4 Fix LP BUG#772309 ...

Analysis:
The method st_select_lex::optimize_unflattened_subqueries()
incorrectly propagated to each subquery the complete
select_options flag set for the whole query. Among other
flags in select_options, this propagated incorrectly the
STRAIGHT_JOIN flag from the upper query to the subquery.

Solution:
During EXPLAIN set only the SELECT_DESCRIBE bit in the
select_options of the subquery.
