A followup patch for Bug#7306 (limit in prepared statements):
don't evaluate subqueries during statement prepare, even if they
are not correlated.
With post-review fixes.
sql/mysql_priv.h:
Add UNCACHEABLE_PREPARE to mark subqueries as non-constant in
mysql_stmt_prepare
sql/sql_lex.cc:
Add a missing assert: noone can call unit::set_limit from
mysql_stmt_prepare.
sql/sql_lex.h:
Comment fixed.
sql/sql_parse.cc:
Mark new SELECT_LEXes as uncacheable if they created during
statement prepare.
sql/sql_prepare.cc:
Switch off the uncacheable flag when prepare is done.
