We have no way to do tests on other architectures other than x86 and ARM
I'm afraid, and some other architectures already seem to have their own
_UPTi_find_unwind_table() implementation, notably:

x86
x86_64
HPPA
ppc64
ia64

So we added this new _UPTi_find_unwind_table() as an ARM only function
for now, but it can be easily used by other architectures if anyone
implement the other necessary bits for them (I think at least the
register offsets are necessary).

Sounds reasonable?

BTW, I'll reword the patch description accordingly to that it explains
that it's not ARM specific, but for now it was only tested on ARM.
