optimiser bug patch.
mysql-test/r/distinct.result:
test results reverted
mysql-test/r/order_by.result:
test results reverted
sql/sql_select.cc:
found_constrain renamed to found_constraint
We don't perform full cartesian product in
case when JOIN BUFFER is used: it was taken
into account.
s->read_time may contain range index read time,
so to get full table scan time is necessary to
call s->table->file->scan_time().
to estimate correctly cost of full table scan we should take into
account rows read and skipped on each iteration.
mysql-test/r/distinct.result:
Fixed test suite: now full scan is used
less often
mysql-test/r/join_outer.result:
Fixed test suite: now full scan is used
less often
