instcombine: Migrate puts optimizations This patch migrates the puts optimizations from the simplify-libcalls pass into the instcombine library call simplifier. All the simplifiers from simplify-libcalls have now been migrated to instcombine. Yay! Just a few other bits to migrate (prototype attribute inference and a few statistics) and simplify-libcalls can finally be put to rest. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168925 91177308-0d34-0410-b5e6-96231b3b80d8
