signal/ia64: Move the ia64 specific si_codes to asm-generic/siginfo.h
Having si_codes in many different files simply encourages duplicate
definitions that can cause problems later. To avoid that merge the
ia64 specific si_codes into uapi/asm-generic/siginfo.h
Update the sanity checks in arch/x86/kernel/signal_compat.c to expect
the now lager NSIGILL and NSIGFPE. As nothing excpe the larger count
is exposed on x86 no additional code needs to be updated.
