Good question. The provenance embedded in the MachineOperand here originates from the ptr_provenance operand in load/store instructions.
Your question does point out that https://reviews.llvm.org/D107356 (aka CodeGen/IntrinsicLowering) is too early  if we want to track the more complex forms
of provenance after lowering.
