unknown 936688feb5 A followup patch for Bug#7306 (limit in prepared statements): ...

don't evaluate subqueries during statement prepare, even if they

  Add UNCACHEABLE_PREPARE to mark subqueries as non-constant in 
  mysql_stmt_prepare

  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.
