Vaughn Iverson 8f2aa9fb48 cpu: conditionally re-enable AVX512 support on darwin/amd64 
Darwin opmask clobbering bug was fixed in kernel version 21.3.0
as released in MacOS 12.2.0. This commit resolves issue by
checking for Darwin AVX512 support via a sysctl call with the
addition of a kernel minimum version check.

The kernel version check is completed without adding new
dependencies to x/sys/cpu. A sysctl call is accomplished by
copying a minimal amount of code from x/sys/unix, to retrieve
only the needed KERN_OSRELEASE value. This code is structured
in the same manner as an existing analogous AIX/PPC64 syscall.

The resulting dotted version string value is then parsed for
numeric comparison with a dependency free function.

All code in this contribution is structured to ease removal of
the special darwin/amd64 codepaths when that OS/arch combination
is eventually no longer supported by golang.

Resolves issue: golang/go#49233, reinstates fix for issue: golang/go#43089

The less syscalls, the better. It also makes the function faster:

John Troy cbf0eb65e7 unix: fix grep syntax to work on non-GNU greps 
CL 432835 changed two grep commands in unix/mkerrors.sh in such a way
that is incompatible with AIX's grep, which, unlike GNU grep, does not
support extended regular expressions without the -E flag. The intent of
this PR is to restore the egrep behavior by invoking grep as grep -E.
My assumption is that GNU grep is not meant to be a requirement to run
mkerrors.sh, and given that, grep -E looks like the most cross-platform
approach.

Example of current (incorrect) behavior on AIX:

bash-5.2$ printf 'SIGHUP\nSIGMAX64\nSIGTERM' | grep -v 'SIGSTKSIZE\|SIGSTKSZ\|SIGRT\|SIGMAX64'
SIGHUP
SIGMAX64
SIGTERM

Behavior before CL 432835:

bash-5.2$ printf 'SIGHUP\nSIGMAX64\nSIGTERM' | egrep -v '(SIGSTKSIZE|SIGSTKSZ|SIGRT|SIGMAX64)'
SIGHUP
SIGTERM

Behavior of proposed change:

bash-5.2$ printf 'SIGHUP\nSIGMAX64\nSIGTERM' | grep -E -v '(SIGSTKSIZE|SIGSTKSZ|SIGRT|SIGMAX64)'
SIGHUP
SIGTERM

OpenBSD's grep behaves the same as AIX for the above commands, which is
why I cast this as GNU vs. non-GNU. I haven't tested any other
implementations.

syscall introduced in Linux 6.4, falling back to HWCAP if riscv_hwprobe
is not supported.  The patch can detect the C, V, Zba, Zbb and Zbs
extensions.  V, Zba, Zbb and Zbs can only be detected on a 6.5 kernel
or later (without backports).
