Remove the bits of the checking code that have never found anything
useful in the last few months of work. Plus, they're timing out on big
test cases.
I'm removing them, as they were never meant to go into production.
Committed to branch.

Remove most sanity checks from check_die(). These were temporarily
there during the branch work and were taking too long to execute while
never finding anything of interest.
