These are different logs/traces. The ones you point out are textual traces for
TCG guest/target instructions (and where to write them). The ones I've added are
for QEMU's tracing infrastructure.

Note that both (-trace vs -d/-D) are also available in system mode (vl.c).

BTW, I forgot to update the series cover according to v3's changes.
