Consider this input:

  #pragma pack(1)
  struct S {
    char    : 8;
    short   : 8;
    short x : 8;
  } s;

Your patch appears to give:

  BitField (0x1001) {
    TypeLeafKind: LF_BITFIELD (0x1205)
    Type: short (0x11)
    BitSize: 8
    BitOffset: 0
  }
  FieldList (0x1002) {
    TypeLeafKind: LF_FIELDLIST (0x1203)
    DataMember {
      AccessSpecifier: Public (0x3)
      Type: 0x1001
      FieldOffset: 0x2
      Name: x
    }
  }

MSVC gives:

  BitField (0x1001) {
    TypeLeafKind: LF_BITFIELD (0x1205)
    Type: short (0x11)
    BitSize: 8
    BitOffset: 8
  }
  FieldList (0x1002) {
    TypeLeafKind: LF_FIELDLIST (0x1203)
    DataMember {
      AccessSpecifier: Public (0x3)
      Type: 0x1001
      FieldOffset: 0x1
      Name: x
    }
  }
