All fields used in the query processing.
Initially this is a list of fields from the query's SQL text.
Then, ORDER/GROUP BY and Window Function code add columns that need to
be saved to be available in the post-group-by context. These extra columns
are added to the front, because this->all_fields points to the suffix of
this list.
