Why not place this before the loop, so that you don't
have to check num_insns == 1?

You're really going to print both ENV and PC tagged with "vaddr"?
That just seems confusing.
Also, terminology. A "basic block" ("bb" by preference, not "bbl"), has a
specific meaning (https://en.wikipedia.org/wiki/Basic_block). What we're
generating here is a TranslationBlock (which may consist of many basic blocks),
and oft contracted within the source as "tb".
