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...

Add support for the GCC binary integer constants extension.

This is required to build the i965 backend with newer versions of mesa.

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.

Make gcc use C99 inline semantics in c99 and gnu99 mode. This was the
original intent, but the functionality wasn't implemented until after
gcc 4.2 was released. However, if you compiled a program that would
behave differently before and after this change, gcc 4.2 would have
warned you; hence, everything currently in the base system is
unaffected by this change. This patch also adds additional warnings
about certain inline function-related bogosity, e.g., using a
static non-const local variable in an inline function.

These changes were merged from a snapshot of gcc mainline from March
2007, prior to the GPLv3 switch. I then ran the regression test suite
from a more recent gcc snapshot and fixed the important bugs it found.
I also squelched the following warning unless -pedantic is specified:

foo is static but used in inline function bar which is not static

This is consistent with LLVM's behavior, but not consistent with gcc 4.3.
