Hi,

This patch does the basic enablement for AMD's first APU architecture -- Bobcat.
It defines -march=btver1 and -mtune=btver1, and lets -march=native correctly
recognizes bobcat. In addition, it does limited tuning for bobcat.

The patch passed bootstrapping and gcc regression tests on x86_64-unknown-linux-gnu.
Programs (cou2000, cpu2006 and polyhedron 2005, etc) compile and run OK with 
-march=btver1 on the bobcat system.

Is it OK to commit to trunk now?

Thanks,

Changpeng
