AMD bdver2 enablement.

- Subject: AMD bdver2 enablement.
Hi,
This patch does the basic enablement for AMD's upcoming bdver2 processor.
It defines -march=bdver2 and -mtune=bdver2, and lets -march=native correctly
recognizes bdver2. At the moment the tuning is mostly a copy of bdver1.
The patch passed bootstrap and the x86 tests.
Is it OK to commit to trunk?
Thanks,
Harsha
