  Fix for valgrind failure (unitialized read Item_func_trig_cond->const_item_cache in get_mm_tree):
   Since get_mm_tree can be called for an instance of Item_func_trig_cond, make Item_func_trig_cond::const_item() return false.
   get_mm_tree will assume Item_func_trig_cond are unknown functions and will not build range access plans for them
