Subject: [PATCH 4/8] x86-64, ia32: Move compat_ni_syscall into C and its own file

From: "H. Peter Anvin" <hpa@...ux.intel.com>

Move compat_ni_syscall out of ia32entry.S and into its own .c file.
Although this is a trivial function, it is not performance-critical,
and this will simplify further cleanups.
