No objections from me anymore.



================
Comment at: llvm/lib/Analysis/ValueTracking.cpp:4785
-  if (isa<FreezeInst>(V))
-    return true;
-  // TODO: Some instructions are guaranteed to return neither undef
----------------
Personally, I'd keep freeze up top, easy case after all ;). No strong opinion though.
