Hi Matt,

As far as I remember the lane mask in live-ins are only supported when subreg liveness is enabled.
Therefore, I believe we should either force the target to track subreg liveness when we see such construct or reject the entry is the target does not track subreg liveness.

What do you think?

Cheers,
-Quentin
