The VPBasicBlock for the miscompiled basic block is the following one:\n```\nvector.body:\n  EMIT vp<%4> = CANONICAL-INDUCTION ir<0>, vp<%7>\n  WIDEN-INDUCTION %d.06 = phi -13, %add2.reass, ir<5>, vp<%0>\n  WIDEN-REDUCTION-PHI ir<%add45> = phi ir<5>\n  EMIT vp<%5> = WIDEN-CANONICAL-INDUCTION vp<%4>\n  EMIT vp<%6> = icmp ule vp<%5>, vp<%3>\n```\nI'm not that familiar with VPlan, though I feel like that either we are not taking into account the active lane, or we should have not emitted a widen instruction in the first place.\n\n(Godbolt: https://llvm.godbolt.org/z/4Wz46ceh1)"
