quick - Parameter to use when reading records.
In the table struct the following information is updated:
quick_keys - Which keys can be used
quick_rows - How many rows the key matches
quick_keys - Which keys can be used
quick_rows - How many rows the key matches
quick_condition_rows - E(# rows that will satisfy the table condition)
IMPLEMENTATION
quick_condition_rows value is obtained as follows:
It is a minimum of E(#output rows) for all considered table access
methods (range and index_merge accesses over various indexes).
The obtained value is not a true E(#rows that satisfy table condition)
but rather a pessimistic estimate. To obtain a true E(#...) one would
need to combine estimates of various access methods, taking into account
correlations between sets of rows they will return.
For example, if values of tbl.key1 and tbl.key2 are independent (a right
assumption if we have no information about their correlation) then the
correct estimate will be:
E(#rows("tbl.key1 < c1 AND tbl.key2 < c2")) =
= E(#rows(tbl.key1 < c1)) / total_rows(tbl) * E(#rows(tbl.key2 < c2)
which is smaller than
MIN(E(#rows(tbl.key1 < c1), E(#rows(tbl.key2 < c2)))
which is currently produced.
TODO
Check if this function really needs to modify keys_to_use, and change the
code to pass it by reference if it doesn't.
* Change the value returned in quick_condition_rows from a pessimistic
estimate to true E(#rows that satisfy table condition).
(we can re-use some of E(#rows) calcuation code from index_merge/intersection
for this)
* Check if this function really needs to modify keys_to_use, and change the
code to pass it by reference if it doesn't.
In addition to force_quick_range other means can be (an usually are) used
to make this function prefer range over full table scan. Figure out if
force_quick_range is really needed.

tree Transformed selection condition, tree->key[idx] holds intervals

idx Number of index to use in tree->keys
