ICE in LTO.

[Bingfeng Mei]

Hello,
I am hit by an ICE in LTO (latest GCC4.5 branch). The problem
is that it shows up in our target/our target-specific application,
so I cannot really reduce test case and file a bug.

Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

It seems that the cloned function lacks node_info as indicated 
by ip-reference.c:1245. I am not familiar with these stuff. Any 
suggestion on where I should look at?  Thanks in advance.

Cheers,
