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.

The third parameter in the call of make_cond_for_table() that
built the pushed condition containing only outer references
was incorrect. This condition appeared for the first time in
the patch fixing bug 729039.

The reason for mtr warning is that collect_mysqld_features() starts mysqld with --datadir=/tmp and this
directory does not exist on Windows.
Fix : instead of passing --datadir=$opt_vardir/tmp in collect_mysqld_features() just use --datadir=.
mysqld does not need a correct directory, just an existing one, as it is started with --help ---verbose -skip-grant-tables.

- Debug build: make DBUG_ASSERT statements really look at the first table
One can't expect cursors to work with semi-join subqueries anyway,
though (which isn't a problem because cursors are not used anywhere)
