H. Peter Anvin e7084fd52e x32: Switch to a 64-bit clock_t
clock_t is used mainly to give the number of jiffies a certain process
has burned.  It is entirely feasible for a long-running process to
consume more than 2^32 jiffies especially in a multiprocess system.
As such, switch to a 64-bit clock_t for x32, just as we already
switched to a 64-bit time_t.

clock_t is only used in a handful of places, and as such it is really
not a very significant change.  The one that has the biggest impact is
in struct siginfo, but since the *size* of struct siginfo doesn't
change (it is padded to the hilt) it is fairly easy to make this a
localized change.

This also gets rid of sys_x32_times, however since this is a pretty
late change don't compactify the system call numbers; we can reuse
system call slot 521 next time we need an x32 system call.
