-print-memoryssa in legacy PM is print<memoryssa> in NPM. Pin tests with -print-memoryssa to legacy PM. Add corresponding tests for NPM where missing. This fixes "unknown pass name 'print-memoryssa'". Some tests still fail in Analysis/MemorySSA due to other passes that haven't been ported. pr43427.ll and pr43438.ll required adding -aa-pipeline=basic-aa, -loop-simplify (since it doesn't run on legacy PM by default), and decrementing some of the MemoryPhi numbers.
