LOG: [NFC] Remove commented cerr debugging loggings

There are some unused cerr debugging loggings in the codes. It is weird
to remain such commented debug helpers in the product.

Added: 
    

Modified: 
    llvm/lib/Analysis/MemoryDependenceAnalysis.cpp
    llvm/lib/Analysis/PHITransAddr.cpp
    llvm/lib/CodeGen/CodeGenPrepare.cpp
    llvm/lib/Transforms/IPO/GlobalOpt.cpp
    llvm/lib/Transforms/Utils/ScalarEvolutionExpander.cpp

Removed:
