[SPARK-11849][SQL] Analyzer should replace current_date and
current_timestamp with literals
We currently rely on the optimizer's constant folding to replace
current_timestamp and current_date. However, this can still result in different
values for different instances of current_timestamp/current_date if the
optimizer is not running fast enough.
A better solution is to replace these functions in the analyzer in one shot.
