I think you mean "with" not "without"? Anyway the total number of register classes decreases from 545 to 543. The diff is:

  +SReg_1_with_lo16_in_M0_CLASS_LO16RegClassID
  -SReg_LO16_XEXEC_HIRegClassID
  -SReg_LO16_XM0RegClassID
  -SReg_LO16_XEXEC_HI_and_SReg_LO16_XM0RegClassID
  -SReg_LO16_XM0_XEXECRegClassID
  -SRegOrLds_32_and_SReg_1RegClassID
  +SReg_32_XEXECRegClassID
  +SReg_32_XEXEC_HI_and_SReg_32_XM0RegClassID
