This is related to the refused enhancement in Issue 8467

Given that issue 8467 says that the "pred" template argument of
std.algorithm.count() can't be changed, then I suggest:

1) To introduce an optimization inside std.algorithm.count(): if the "pred"
template argument was not changed by the programmer (so it's equal to "true"),
and the given range defines a length, then to return that length value.

2) To deprecate std_range.walkLength() because now its purposes are replaced by
std.algorithm.count().
