CL 294430 made packages in std and cmd modules use Go 1.17 gofmt format,
adding //go:build lines. This change applies the same formatting to some
more packages that 'go fmt' missed (e.g., syscall/js, runtime/msan), and
everything else that is easy and safe to modify in bulk.
Consider the top-level test directory, testdata, and vendor directories
out of scope, since there are many files that don't follow strict gofmt
formatting, often for intentional and legitimate reasons (testing gofmt
itself, invalid Go programs that shouldn't crash the compiler, etc.).
That makes it easy and safe to gofmt -w the .go files that are found
with gofmt -l with aforementioned directories filtered out:
$ gofmt -l . 2>/dev/null | \
grep -v '^test/' | \
grep -v '/testdata/' | \
grep -v '/vendor/' | wc -l
51
None of the 51 files are generated. After this change, the same command
prints 0.
For #41184.

Currently we don't use sigaltstack on darwin/arm64, as is not
supported on iOS. However, it is supported on macOS. Use it.
(iOS remains unchanged.)

Introduce GOOS=ios for iOS systems. GOOS=ios matches "darwin"
build tag, like GOOS=android matches "linux" and GOOS=illumos
matches "solaris". Only ios/arm64 is supported (ios/amd64 is
not).
GOOS=ios and GOOS=darwin remain essentially the same at this
point. They will diverge at later time, to differentiate macOS
and iOS.
Uses of GOOS=="darwin" are changed to (GOOS=="darwin" || GOOS=="ios"),
except if it clearly means macOS (e.g. GOOS=="darwin" && GOARCH=="amd64"),
it remains GOOS=="darwin".
Updates #38485.

Like GOOS=android which implies the "linux" build tag, GOOS=illumos
implies the "solaris" build tag. This lets the existing ecosystem of
packages still work on illumos, but still permits packages to start
differentiating between solaris and illumos.

With GCC 7 (not yet released), cgo fails with errors like
./sigaltstack.go:65:8: call of non-function C.restoreSignalStack
I do not know precisely why. Explicitly declaring that there are no
arguments to the static function is a simple fix for the debug info.

If non-Go code calls sigaltstack before a signal is received, use
sigaltstack to determine the current signal stack and set the gsignal
stack to use it. This makes the Go runtime more robust in the face of
non-Go code. We still can't handle a disabled signal stack or a signal
triggered with SA_ONSTACK clear, but we now give clear errors for those
cases.
Fixes#7227.
