If we're debugging the SimplifyCFG pass, we _REALLY_ don't want to use it for
...
narrowing, no matter what.

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.

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

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!

Use the list reducer to improve convergence speed and to support crashes that

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

Make bugpoint *much* more powerful, giving it the capability to delete instructions

out of a large function to reduce it.
