P4
We only emit IR per bytecode to IGV if the specified verbosity level is >=5.
N=5: additionally, after parsing every bytecode (very slow)

I think we should match this in C2 Parse::do_one_bytecode().
Currently, we conservatively check C->should_print_igv(1) and only emit IR per bytecode when level >= 5. It's wasteful for level>=1 and <= 4. we eval "jio_snprintf(buffer, sizeof(buffer), "Bytecode %d: %s", bci(), Bytecodes::name(bc()));' but emit nothing.
