     First is the initialization and goto.
     CHECK: store i32 5
     CHECK-NEXT: br label %[[GOTO_TARGET:.+]]

     Then comes the initialization of the for loop variable.
     CHECK: store i32 0
     CHECK-NEXT: br label %[[FOR_COND:.+]]

     Then comes the for loop condition check label followed eventually by the
     for loop body label.
     CHECK: [[FOR_COND]]:
     CHECK: {{.+}} = icmp slt i32 {{.+}}, 10
     CHECK: [[FOR_BODY:.+]]:
     CHECK: {{.+}} = icmp sgt i32 {{.+}}, 2

     Then comes the then branch of the if statement.
     CHECK: %[[I:.+]] = load i32,
     CHECK-NEXT: %[[INC:.+]] = add nsw i32 %[[I]], 1
     CHECK-NEXT: store i32 %[[INC]],

     Eventually, we get to the goto label and its call
     CHECK: [[GOTO_TARGET]]:
     CHECK-NEXT: call void @foo()
