I have sufficient reviews for 6863023 as of webrev.03, but the GC
interactions are (sigh) more subtle than I anticipated, and I want to
get it right.
Here is a fresh layer of changes, required to ensure that strong-root
nmethods get scavenged exactly once.

These changes fix some double-tracing bugs, but they are not correct.
However, they are not right yet. What I'm asking for now is (a)
further advice for structuring the nmethod-walking code correctly, and
(b) help spotting bugs.
