This adds -fchecking as a way to enable internal consistency checks

I remember that Jakub proposed to use __builtin_expect with
flag_checking. I wonder, if it is possible to implement without hacking
AWK scripts just for this particular case? For example, to define
flag_checking to something like
#define flag_checking __builtin_expect (flag_checking_val, CHECKING_P)
(provided that flag_checking_val is the actual value got from
command-line options).
I think this ought to be a follow-up item. And yes, we're going to need
some level of indirection so that we're not writing __builtin_expect all
over the place.
