This fixes the unexpected growth of stack in child process, which
is caused by stack checking code in runtime.sigfillset called from
runtime.sigset while clearing the signal handlers in child process.
The redundant stack checking code is generated due to missing
'//go:nosplit' directive that should be annotated for
runtime.sigfillset.
Fixes #43066
Updates #21314

Follow CL 93655 which removed the (commented-out) usage of this
function.
Also remove unused constant _RLIMIT_AS and type rlimit.

On 64-bit big-endian GNU/Linux machines we need to treat sigset as a
single uint64, not as a pair of uint32 values. This fix was already made
for s390x, but not for ppc64 (which is big-endian--the little endian
version is known as ppc64le). So copy os_linux_390.x to
os_linux_be64.go, and use build constraints as needed.
Fixes #17361

The OS-independent sigmask type was not pulling its weight. Replace it
with the OS-dependent sigset type. This requires adding an OS-specific
sigaddset function, but permits removing the OS-specific sigmaskToSigset
function.

Unify the OS-specific versions of msigsave, msigrestore, sigblock,
updatesigmask, and unblocksig into single versions in signal_unix.go.
To do this, make sigprocmask work the same way on all systems, which
required adding a definition of sigprocmask for linux and openbsd.
Also add a single OS-specific function sigmaskToSigset.
