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.
