Add experimental support for amdfam10/barcelona from the GCC 4.3 branch.
Initial support for the AMD barcelona chipsets has been available in the
gcc43 branch under GPLv2 but was not included when the Core 2 support
was brought to the system gcc.
AMD and some linux distributions (OpenSUSE) did a backport of the amdfam10
support and made them available. Unfortunately this is still experimental
and while it can improve performance, enabling the CPUTYPE may break some
C++ ports (like clang).
Special care was taken to make sure that the patches predate the GPLv3
switch upstream.
