Fixed in https://reviews.llvm.org/rL281784

This is what it reduced to: 

define i8* @zot() safestack {
bb:
  %tmp = alloca i8*, align 8
  %tmp2 = bitcast i8** %tmp to i8*
  br label %bb3

bb3:                                              ; preds = %bb3, %bb
  call void @llvm.lifetime.start(i64 8, i8* nonnull %tmp2)
  %tmp4 = call i32 @wombat(i8** nonnull %tmp)
  indirectbr i8* undef, [label %bb3]
}

declare i32 @wombat(i8**)
