Monty 013ba37ae2 Fix cost calculation in test_if_cheaper_ordering() to be cost based ...

The original code was mostly rule based and preferred clustered or
covering indexed independent of cost.

There where a few test changes:
- Some test changed from using filesort to index or table scan. This
  happened when most of the rows had to be sorted and the ORDER BY could
  use covering or a clustered index (innodb_mysql, create_spatial_index).
- Some test changed range to filesort. This where mainly because the range
  was scanning most of the rows or using index scan + row lookup and
  filesort with table scan is cheaper. (order_by).
- Change in join_cache was because sorting 2 rows is faster than retrieving
  10 rows.
- In selectivity_innodb.test one test changed to use a cheaper index.
