Review comment:
Let's get rid of `TEMPORARY TABLE`. It was a mistake and we've almost
removed everything about `TEMPORARY TABLE` in Spark, only a few parser rules
are left for backward compatibility reason.
To clarify, there is no `TEMPORARY TABLE` in Spark, it never had. Spark only
has TABLE, VIEW and TEMP VIEW.
