[PATCH] D137615: [BOLT][Instrumentation] Instrument leaves from spanning tree

@rafauler you’re right, thanks for explanation.
I was confused by the following checking

if (STOutSet[&BB].size() == 0)

Because if for some reason the BB is not in the spanning tree, the default constructor for this base block is called and it is inserted into the STOutSet with 0 number of successros.
Therefore the insturmentation snipet is inserted.
But now there is only one reason for that, a BB is a tree leaf.
