Filtering by @execution_count is non-trivial.
In the Query Store DMVs, execution counts only exist in
sys.query_store_runtime_stats.
That DMV has no query_id column (or anything similar),
but we promised that @execution_count would filter by the
number of executions of the query.
The best column for us in the DMV is plan_id, so we need
to get from there to query_id.
Because we do most of our filtering work in #distinct_plans,
we must also make what we do here compatible with that.

In conclusion, we want produce a temp table holding the
plan_ids for the queries with @execution_count or more executions.

This is similar to the sort-helping tables that you are
about to see, but easier because we do not need to return or sort
by the execution count.
We just need to know that these plans have enough executions.

Regression mode differs significantly from our defaults.
In this mode, we measure every query hash in the time period
specified by @regression_baseline_start_date and
@regression_baseline_end_date ("the baseline time period").
Our measurements are taken based on the metric given
by @sort_order.
For all of the hashes we have taken measurements for, we
make the same measurement for the time period specified
by @start_date and @end_date ("the current time period").
We then compare each hashes' measurement across the two
time periods, by the means specified by
@regression_comparator and take the @top results ordered by
@regression_direction.
We then get every plan_id in both time periods for those
query hashes and carry on as normal.

This gives us three immediate concerns. We:
   1) Need to adjust our @where_clause to refer to the
      baseline time period.
   2) Need all of the queries from the baseline time
      period (rather than just the @top whatever).
   3) Are interested in the query hashes rather than
      just plan_ids.

We address part of the first concern immediately.
Later, we will do some wicked and foul things to
modify our dynamic SQL's usages of @where_clause
to use @regression_where_clause.
