--- Comment #12 from Vineet Gupta <vineetg at gcc dot gnu.org> ---
To recap, this needs 2 fixes

 (1) Prevent BB with abnormal edges from getting into LCM computations [1]
     This clears them from Anticipated and Transparent bitmaps

 (2) Despite above, LCM earliest output can still have BB with such edges.
     So prevent vsetvl hoisting into non-transparent BB [2]
     This was anyhow needed for PR/119547
