Guarded loser tree/tournament tree, either copying the whole element into the tree structure, or looking up the element via the index.
This is a base class for the LoserTreeCopy<true> and <false> classes.
Guarding is done explicitly through one flag sup per element, inf is not needed due to a better initialization routine. This is a well-performing variant.
