Arthur Eubanks d30f886c6b [MSSA][NewPM] Handle tests with -print-memoryssa
-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.
