5f73e38548 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.

286921e8d2 Speed up convergence significantly and also reduce the size of testcases by making large portions of a function's CFG dead at a time.

f607b79bc7 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!

ba386d943f * 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
