Added code that ensures that we don't try to reduce an empty vector of basic
...
blocks.
This fixes the bugpoint regressions.

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.

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!

only occur when multiple passes interact or when multiple functions exist in a module

* 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
