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.

Fix various clang-tidy warnings
...
When I tried to add cool new clang-tidy 14 warnings, I noticed that the
current clang-tidy settings already produce a ton of warnings. This
commit addresses many of these. Almost all of them were non-critical,
i.e. C vs. C++ style casts.

This check suggests replacing <Container>.count() by
