It is not a simple refacotring...

I am afraid not. We should try this approach, because this will benefit
all targets. IMO, handling unavailable memory in general frame
unwinding is more important.

b.t.w, I am still not confident on the arm software single step in
GDBserver on some cases, such as branch-to-self (".L2: b .L2") and
single step with signal. ARM tracepoint patches can go in after these
issues are resolved (I am working on these issues).
