Make a version of Position::do_move() without the givesCheck parameter

Browse Source 
In 10 of 12 calls total to Position::do_move()the givesCheck argument is
simply gives_check(m). So it's reasonable to make an overload without
this parameter, which wraps the existing version.

No functional change.
