One suggestion would be to make unwind_state part of the probe context data
which is staticly allocated. Then we could pass the state from the
[u]context-unwind.stp script-level for use with the unwinder.
It does add a few hundred bytes even for probes points that don't do unwinding,
and currently only x86 uses the dwarf unwinder.
