systemc: Implement sc_fifo::dump and improve sc_fifo::print.
The print function is supposed to print both pending and committed
writes, apparently.
Accellera's implementation of sc_fifo uses a ring buffer to store the
entries and manages a head and tail pointer to keep track of what's
full, etc. Their dump function prints that whole buffer using the
indexes. When not using a ring buffer, there's no easy way to determine
what those indexes should be.
Fortunately the test that uses dump never moves away from the base of
the ring buffer, so I can get the same effect (which also makes sense
on its own) by printing the index into the fifo instead.
