Functions
static LogicalResult	verifyWidthsMatch (XbarOp op, ArrayRef< WidthField > fields, PortType port, const Twine &portDesc, PortType reference, const Twine &referenceDesc)
	Verify that port agrees with reference on each of the widths in fields.

	The downstream port and window covering address, or a null window if no downstream port covers it.

	The outstanding writes and reads a routing op sends down downstream, from the upstream ports whose windows reach it.
static LogicalResult	verifyOutstanding (Operation *op, const Twine &portDesc, PortType port, std::pair< uint64_t, uint64_t > reaching, const Twine &sourceDesc)
	Verify that port holds exactly the outstanding requests reaching it.
