The logic in the -pruneeh pass is completely flawed.  It's not clear how it ever
could have worked, but it is now the cause of several failures in
SingleSource/UnitTests/SetjmpLongjmp.

Fixed.  Patch here:
http://mail.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20040202/011331.html

Testcases are in SingleSource/UnitTests/SetjmpLongjmp, which all pass now, in
all configurations.
