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 60430423c9 Fix a nasty bug where the ConstantMerge pass was invalidating the TargetData pass
even though it was immutable.  Immutable passes should never end up in CurrentAnalyses!
