Do not clobber r12 for ia64 syscalls.

GCC mainline now gives errors for an asm that clobbers the stack
pointer.  According to
<https://gcc.gnu.org/ml/gcc-patches/2018-12/msg00932.html> GCC
previously ignored such a clobber; thus, this patch removes it from
the clobbers for ia64 syscalls.

Tested with build-many-glibcs.py for ia64-linux-gnu.

* sysdeps/unix/sysv/linux/ia64/sysdep.h (ASM_CLOBBERS_6_COMMON):
Do not clobber r12.
