aarch64: Consolidate NPTL/non versions of vfork

At the same time, incorporate the 0 -> 0x80000000 mapping
of the pid expected by raise.c.

aarch64: Consolidate NPTL/non versions of clone

At the same time, rely on non-clobbered registers across syscall
so that we eliminate the stack frame that we previously ignored
in the unwind info.

aarch64: Rely on syscalls preserving registers

In several cases we've had asm routines rely on syscalls not clobbering
call-clobbered registers, and that's now deemed ABI. So take advantage
of this in the INLINE_SYSCALL path as well.

Shrinks libc.so by about 1k.

One push instead of N; use stp/ldp to halve the insns.

aarch64: Pass regno parameter to SINGLE_THREAD_P

Use cbz instead of cmp+b.eq.

arm,aarch64: Remove SINGLE_THREAD_P_PIC

This macro was removed by

2005-11-16 Daniel Jacobowitz <email address hidden>

but not applied to the (still separate) eabi port so necro'd
when the eabi port superceded the old abi. It was thence
copied into the new AArch64 port.
