Update.

* sysdeps/unix/sysv/linux/ia64/sysdep.h
(GAS_ALIGN_BREAKS_UNWIND_INFO): Define this macro to indicate
that all existing GAS versions have a problem with .align inside
a function.
* sysdeps/ia64/memccpy.S: Work around GAS_ALIGN_BREAKS_UNWIND_INFO bug.
* sysdeps/ia64/memcpy.S: Likewise.
* sysdeps/ia64/memset.S: Likewise.
* sysdeps/ia64/memmove.S: Likewise. Also move the jump-table to
out of .text into .rodata, where it belongs.
* sysdeps/unix/sysv/linux/ia64/pipe.S: There is no need to
save/restore input-arguments, because they're necessarily
preserved by the kernel to support syscall-restart.
