b078889a6b Revert r259619:
Fixes GCC libstdc++/29286

The fix seems to work for amd64 but causes segfaults on powerpc.
At this time gcc is much more important on powerpc than on amd64.

5917560e17 Bring a couple of fixes for gcc optimizations.
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.

a6c34d9e26 Revert r236962 - Experimental amdfam10/barcelona support.
The patches are unexpectedly causing gcc to fail while
building ports/graphics/ImageMagick even when the cpu
flags are not used.

b28518a59a 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.

497e80a371 Reorganize the gcc vendor import work area. This flattens out a bunch
of unnecessary path components that are relics of cvs2svn.
