the visit function.  The worklist is for when their lattice value changes.

b258ffd600 Allow for easy detection of when a "default" TargetData is created by the 
passmanager, which is never the right thing to do.

8a549d117d 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.

9c2869eca8 Speed up convergence significantly and also reduce the size of testcases by making large portions of a function's CFG dead at a time.

15574dd30f 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!

6e2ea5ccff 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!
