+; CHECK: # %bb.2: # %if.then
+; CHECK: bl bar
+; CHECK: .LBB0_3: # %if.then2
----------------
Change the three `CHECK: bl bar` to `CHECK-NEXT: bl bar`

It makes the reader clear they are first instructions in their basic blocks and there will be a friendly error message if things go wrong.

```
; CHECK:      # %if.then2
; CHECK-NEXT:  bl bar
```

+; CHECK: .LBB0_3: # %if.then2
----------------
ditto
