Chris Lattner 0347cda8b8 Rename Kept -> Suffix 
FIX problem where we were incorrectly putting the prefix of the list into the "suffix" list.

Chris Lattner 65e5f653fd Big programs have tons of global variable initializers, and most passes don't care 
about them.  Try to delete them if it doesn't affect the passes.

Chris Lattner f32939bbc9 Speed up convergence significantly and also reduce the size of testcases by making large portions of a function's CFG dead at a time.

Chris Lattner de39f2bdac The big fix is this change: 
-    if (I->isExternal() && !Functions.count(I))
+    if (!I->isExternal() && !Functions.count(I))

We were not actually deleting any functions from the module!

Chris Lattner 514c02eb26 * Reduce the number of useless bytecode files produced by bugpoint. 
- This also speeds it up as the bytecode writer isn't terribly fast.
* Add a new cleanup pass after everything else to run -funcresolve -globaldce
