Subject: Clear TT before running 'bench'
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=8b00e50cb74392c24938c0019ac528a9feabd614

Clear TT before running 'bench'

Now that we can call bench multiple times
from command prompt we need to ensure searched
nodes remain constant across different runs.

Spotted by Bálint Pfliegel.

No functional change.
