  Log Message:
  -----------
  [CodeGen] Support --print-changed for legacy codegen IR passes (#202252)

--print-changed is only wired into MachineFunctionPass (
https://reviews.llvm.org/D133055), so the IR-level passes in the codegen
pipeline (atomic-expand, codegenprepare, etc.) are not reported.

Report them from FPPassManager/MPPassManager instead, via a new
Pass::printIRUnit hook that MachineFunctionPass overrides to print MIR.
Analyses are skipped, matching the new pass manager.
