Split cost calculations into fetch and total
This patch causes no changes in costs or result files.
Changes:
- Store row compare cost separately in Cost_estimate::comp_cost
- Store cost of fetching rows separately in OPT_RANGE
- Use range->fetch_cost instead of adjust_quick_cost(total_cost)
This was done to simplify cost calculation in sql_select.cc:
- We can use range->fetch_cost directly without having to call
adjust_quick_cost(). adjust_quick_cost() is now removed.
Other things:
- Removed some not used functions in Cost_estimate
