Call into libSystem (Darwin's libc equivalent) to do system calls.
Raw syscalls are not a supported ABI on Darwin, they want us to use
libSystem calls instead.

The stdlib has already been converted to this new regime.  This
package is vendored into the stdlib, so we need to fix it also, then
vendor it in again.

Because this package isn't tied to a Go release, we need to keep the
old code around and use the new code only for 1.12 and up.

Use the arm_sync_file_range to implement SyncFileRange.

This is an alias for sync_file_range2 syscall which is already used to
implement SyncFileRange on ppc64x. These have the order of the flags and
offset arguments reversed in order to fit the syscall arguments within 6
registers.

IoctlSetPointerInt is necessary for interacting with the PPP kernel
driver, which wants it passed as a pointer to int, rather than the
more conventional int cast as a pointer.

We can technically do this already with
IoctlSetInt(int(uintptr(unsafe.Pointer(&foo)))), but that's just
masking the operation we're trying to execute in the first place,
and relying on the internals of IoctlSetInt to do the right
inverse transformation.

When using -linkshared, the external linker on ppc64x cannot
always handle the direct branch to syscall.Syscall and similar
similar functions when the offset is too far. Instead it should
be done as a BL which can then be called through a procedure
linkage table entry.

This change removes functions Syscall, Syscall6,
RawSyscall, RawSyscall6 from asm_linux_ppc64x.s and instead
creates Go functions which call their corresponding
functions in the syscall package. As Go functions, they can be
inlined with the help of CL 147361.
