    M llvm/lib/CodeGen/GlobalISel/LegalizerHelper.cpp
    M llvm/lib/CodeGen/GlobalISel/Utils.cpp

  Log Message:
  -----------
  [GlobalISel] Add a shared matcher for memcpy-family instructions (NFC) (#201766)

This is a precursor to adding TableGen patterns for these combines so
the handwritten C++ handling can be removed from prelegalizer combiners.

There's a fair bit of code movement, but it should be NFC.
findGISelOptimalMemOpLowering is unchanged.
