commit 5738a9825160b4fdc76882d30578c4ae06c058f5

Only collect and emit unwind data in translator if the session needs it.
When we hit the translator the session already knows whether or not it
will possibly need the unwind data. Only collect and emit it, if the
session does. This can save writing out tens of MB to stap-symbols.h
for simple scripts that never call any backtrace() function.

Remove preempt_disable from unwind hotpath.
We only need to preempt_disable when we fail to find a kernel module to
unwind through so we can call __module_text_address.
