7861aae155 cpu: pretend AVX-512 is disabled on Darwin 
Darwin doesn't save/restore the AVX-512 mask registers when
processing a signal. Go generates lots of signals, which cause
the mask registers to randomly get clobbered. Better to pretend
that AVX-512 isn't supported.

Go 1.16 renamed the iOS port from darwin/arm64 to ios/arm64 and
darwin/arm64 was repurposed for the macOS ARM64 port (see
https://golang.org/doc/go1.16#darwin).

Now that Go 1.16 is the oldest supported release, the ios tag can be
used exclusively to detect iOS and TestGetwd can use the same list of
directories as other systems.

1cf2251ac2 unix: implement ppoll in terms of poll on Linux 
Android's Bionic libc installs a seccomp filter that allows ppoll but
not poll. This has been fine for arm64, where we already implement poll
in terms of ppoll, but not the other architectures, such as amd64, which
runs on Chromebooks, and currently leads to crashes.

This commit implements poll in terms of ppoll on the remaining
architectures and makes this common code, so that everyone uses the more
modern syscall.

d61c044b16 unix: implement Pipe using pipe2 syscall on all linux platforms 
Most architectures currently already implement Pipe using the pipe2
syscall. Only 386, amd64, mips{,le}, ppc and sparc64 still use the pipe
syscall. However, some systems (e.g. Android seccomp policies) block
that syscall, see golang/go#40828 for an example.

The pipe2 syscall was added in Linux kernel version 2.6.27. The minimum
required Linux kernel version for Go 1.18 will be changed to 2.6.32
per golang/go#45964 so it is possible to unify the implementation of
Pipe using the pipe2 syscall.

Same as CL 350530 did for package syscall.
