b680697cce Initialize POD members of ASTs to make it less error-prone 
The cost of initializing members is insignificant in compare to parsing,
while the cost of the error is high.

773a5bbbaa Optimize predicate with toYear converter 
The date converters, such as toYear, are widely used in the where
clauses of the SQL queries, however, these conversions are often
expensive due to the complexity of the calendar system.

The function preimage is found an optimization for the predicates
with the converters. Given a predicate, toYear(c) = y, we could
convert it to its equivalent form: c >= b AND c <= e, where b is
"y-01-01" and e is "y-12-31". The similar transformation applies
to other comparisons (<>, <, >, <=, <=).

This commit implemented the above transformation at the AST level
by adding a new pass in the TreeOptimizer and a new AST visitor
for in-place replacing the predicates of toYear with the converted
ones.
