Added test cases for preceding test

This includes all test changes from
"Changing all cost calculation to be given in milliseconds"
and forwards.

Some of the things that caused changes in the result files:

- As part of fixing tests, I added 'echo' to some comments to be able to
  easier find out where things where wrong.
- MATERIALIZED has now a higher cost compared to X than before. Because
  of this some MATERIALIZED types have changed to DEPENDEND SUBQUERY.
  - Some test cases that required MATERIALIZED to repeat a bug was
    changed by adding more rows to force MATERIALIZED to happen.
- 'Filtered' in SHOW EXPLAIN has in many case changed from 100.00 to
  something smaller. This is because now filtered also takes into
  account the smallest possible ref access and filters, even if they
  where not used. Another reason for 'Filtered' being smaller is that
  we now also take into account implicit filtering done for subqueries
  using FIRSTMATCH.
  (main.subselect_no_exists_to_in)
  This is caluculated in best_access_path() and stored in records_out.
- Table orders has changed because more accurate costs.
- 'index' and 'ALL' for small tables has changed to use 'range' or
   'ref' because of optimizer_scan_setup_cost.
- index can be changed to 'range' as 'range' optimizer assumes we don't
  have to read the blocks from disk that range optimizer has already read.
  This can be confusing in the case where there is no obvious where clause
  but instead there is a hidden 'key_column > NULL' added by the optimizer.
  (main.subselect_no_exists_to_in)
- Scan on primary clustered key does not report 'Using Index' anymore
  (It's a table scan, not an index scan).
- For derived tables, the number of rows is now 100 instead of 2,
  which can be seen in EXPLAIN.
- More tests have "Using index for group by" as the cost of this
  optimization is now more correct (lower).
- A primary key could be preferred for a normal key, even if it would
  access more rows, as it's faster to do 1 lokoup and 3 'index_next' on a
  clustered primary key than one lookup trough a secondary.
  (main.stat_tables_innodb)

Notes:

- There was a 4.7% more calls to best_extension_by_limited_search() in
  the main.greedy_optimizer test.  However examining the test results
  it looked that the plans where slightly better (eq_ref where more
  chained together) so I assume this is ok.
- I have verified a few test cases where there was notable/unexpected
  changes in the plan and in all cases the new optimizer plans where
  faster.  (main.greedy_optimizer and some others)
