Manos Koukoutos ef4de56695 [turbofan] Optimize BranchConditions in BranchElimination 
When BranchElimination has to find the common prefix of a set of
BranchConditions in a Merge, it has to traverse a number of linked lists
of individual conditions, which is inefficient.
This CL improves its performance by grouping conditions between an
IfTrue/IfFalse and a Merge in a single entry of BranchConditions.
Additional change: Improve documentation of FunctionalList.
