Marco Costalba cbcc581a86 Use past SE information also for success cases ...

If singular extension search was succesful in the past then
skip another the SE search and extend of one ply.

Another way to mitigate the cost of SE at the price of
some more spurious extension, but on 90% of cases info
is correct.
