SelectionDAGDumper: Avoid unnecessary newlines

Before:
  t0 = EntryToken:ch

    t0: <multiple use>
        t0: <multiple use>
      t1 = CopyFromReg:v4f32,ch t0, Register:v4f32  %vreg0

      t25 = IMPLICIT_DEF:v4f32

    t26 = HADDPSrr:v4f32 t1, t25

  t23 = CopyToReg:ch,glue t0, Register:v4f32  %XMM0, t26

    t23: <multiple use>
    t23: <multiple use>
  t24 = RETQ:ch Register:v4f32  %XMM0, t23, t23:1

After:
    t0: <multiple use>
        t0: <multiple use>
      t1 = CopyFromReg:v4f32,ch t0, Register:v4f32  %vreg0
    t26 = X86ISD::FHADD:v4f32 t1, undef:v4f32
  t23 = CopyToReg:ch,glue t0, Register:v4f32  %XMM0, t26
    t23: <multiple use>
    t21 = TargetConstant:i16<0>
    t23: <multiple use>
  t24 = X86ISD::RET_FLAG:ch t23, t21, Register:v4f32  %XMM0, t23:1
