This is enabled by default. Drop explicit uses in preparation for
removing the option.
Also drop RUN lines that are now the same (typically modulo a
-verify-memoryssa option).
-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.

MemoryPhis should be added in the IDF of the blocks newly gaining Defs.
This includes the blocks that gained a Phi and the block gaining a Def,
if the block did not have one before.
Resolves PR43427.
