The GCC4.3 branch contains some optimization fixes
that were not considered regressions and therefore
were never backported. We are bringing a couple of
them that are under GPLv2 since they were made
before the license switch upstream.
While here, add the GCC revision numbers in the
log.

The patches are unexpectedly causing gcc to fail while
building ports/graphics/ImageMagick even when the cpu
flags are not used.

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.
