History
Nick Lewycky 295e397220 Teach simplifycfg to recompute branch weights when merging some branches, and 
to discard weights when appropriate. Still more to do (and a new TODO), but
it's a start!

dce-cond-after-folding-terminator.ll
Add a parameter to ConstantFoldTerminator() that callers can use to ask it to also clean up the condition of any conditional terminator it folds to be unconditional, if that turns the condition into dead code. This just means it calls RecursivelyDeleteTriviallyDeadInstructions() in strategic spots. It defaults to the old behavior.
