LOG: [JumpThreading] Remove LVI printer flag

This patch removes the -print-lvi-after-jump-threading flag now that we
can print everything in the LVI cache using the print<lazy-value-info>
pass.

Added: 
    

Modified: 
    llvm/lib/Transforms/Scalar/JumpThreading.cpp
    llvm/test/Analysis/LazyValueAnalysis/lvi-after-jumpthreading.ll
