af353127 - MachinePipeliner: Fix using getUniqueVRegDef on a physical register (#216793)

MachinePipeliner: Fix using getUniqueVRegDef on a physical register (#216793) Currently this is permissive and doesn't assert when called with a physical register, but I'm working on changing this edge case. No current observable change. Co-authored-by: Claude (Claude-Opus-4.8) <noreply@anthropic.com>
