This is a target issue dealing with TLS I think.  UNSPEC in general with what
is called non-delegitimized is always a target issue.

I guess just
        (const_ok_for_output_1): Don't complain about TLS UNSPECs.
hunk from my http://gcc.gnu.org/ml/gcc-patches/2010-08/msg01475.html
should be applied separately, unless the whole patch is approved soon.

Jakub, this was originally reported on 4.5, do you have plans on backporting
the change to the 4.5 branch?
