We should ignore alias when we check if table was already marked as temporary
when we calculate set of tables to be prelocked. Otherwise we will erroneously
treat tables which are used in same routine and have same name but different
alias as non-temporary.

Absence of table in left part of LEFT/RIGHT join wasn't checked before
name resolution which resulted in NULL dereferencing and server crash.

Modified rules: 
"table_ref LEFT opt_outer JOIN_SYM table_ref" and "table_ref RIGHT opt_outer 
JOIN_SYM table_ref"
NULL check is moved before push_new_name_resolution_context()

Item equal objects are employed only at the optimize phase. Usually they are not
supposed to be evaluated.  Yet in some cases we call the method val_int() for
them. Here we have to take care of restricting the predicate such an object
represents f1=f2= ...=fn to the projection of known fields fi1=...=fik.

Added a check for field's table being const in Item_equal::val_int().
If the field's table is not const val_int() just skips that field when
evaluating Item_equal.
