If your analysis shows that all the syscalls were always wired up (in both
places, syscall table and asm/unistd.h) at the same time, you can just use
a single __ASSUME (or if by mistake some architectures were only partially
wired up, you could still use a single __ASSUME if it's conservatively
safe).
