Do we want to preserve the synchronized statement itself in the graph? I.e. call defaultAction(synchro, BranchKind.STATEMENT) or w/e somewhere? Currently it looks like the synchronized is unrolled and no trace of it is left?

Ideally yes, but in the current CFG model this is not possible in any way I like. This is one of the things I would like to improve with the redesign started in #5742

Currently, a
synchronizedstatement is completely ignored in the CFG. This PR adds it to the CFG properly.
