Ping: patch to remove the old RA

[Vladimir Makarov <vmakarov at redhat dot com>]

The original patches were posted on

http://gcc.gnu.org/ml/gcc-patches/2008-12/msg00613.html
http://gcc.gnu.org/ml/gcc-patches/2008-12/msg00741.html

I am sending an updated version of the patch here because a few recent 
IRA patches resulted in the patch updates too.

The current patch was successfully bootstrapped on x86, x86_64, itanium, 
and ppc64 on yesterday trunk.

Ok to submit?
