2d278bb89e gcc: Add support for label attributes and "unavailable" attribute.
Apple GCC has extensions to support for both label attributes and
an "unavailable" attribute. These are critical for objc but are
also useful in regular C/C++.

Apparently at least the label attributes might have found their way to
upstream GCC but the code doesn't seem available on the GPLv2 tree so
we are taking the code directly from Apple. To make this clearer we
are preserving the annoying "APPLE LOCAL" tags and the ChangeLogs
when they are available.

8b3d3bafec Use correct casts in gcc's emmintrin.h for the first arguments of the
following builtin functions:

* __builtin_ia32_pslldi128() takes __v4si instead of __v8hi
* __builtin_ia32_psllqi128() takes __v2di instead of __v8hi
* __builtin_ia32_psradi128() takes __v4si instead of __v8hi

This should fix the following errors when building the LINT kernel with
gcc:

sys/crypto/aesni/aesni_wrap.c:191: error: incompatible type for argument 1 of
'__builtin_ia32_psradi128'
sys/crypto/aesni/aesni_wrap.c:195: error: incompatible type for argument 1 of

Initial support for the AMD amdfam10 chipsets has been available in the

a backport of the amdfam10 support and made it available.

This is a revised subset of the support initially brought in in r236962

it is still recommended to set the CPUTYPE with caution.
