docs: Creates a control flow graph edge corresponding to an exception handler.
  The default implementation of this method delegates to
  {@link #newControlFlowExceptionEdge(int, int)
  newControlFlowExceptionEdge(int, int)}. It can be overridden in order to
  construct the control flow graph of a method (this method is called by
  the {@link #analyze analyze} method during its visit of the method's
  code).
  
  @param insn
  an instruction index.
  @param tcb
  TryCatchBlockNode corresponding to this edge.
  @return true if this edge must be considered in the data flow analysis
  performed by this analyzer, or false otherwise. The default
  implementation of this method delegates to
  {@link #newControlFlowExceptionEdge(int, int)
  newControlFlowExceptionEdge(int, int)}.
