add support to gcc for AES and PCLMUL intrinsics... This addes the
-maes option, but not the -mpclmul option as I ran out of bits in
the 32 bit flags field... You can -D__PCLMUL__ to get this, but it
won't be compatible w/ clang and modern gcc...

GCC: bring back experimental support for amdfam10/barcelona CPUs.

Initial support for the AMD amdfam10 chipsets has been available in the
gcc43 branch under GPLv2. AMD and some linux distributions (OpenSUSE) did
a backport of the amdfam10 support and made it available.

This is a revised subset of the support initially brought in in r236962
and later reverted. The collateral efects seem to have disappeared but
it is still recommended to set the CPUTYPE with caution.

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.

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.
