Mark Langen 694045abd8 Implement MxVector2/3/4 and MxMatrix (#100) ...

* All of the MxVectors share an inheritance chain. MxVector4 inherits
  from MxVector3 which inherits from MxVector2.

* They all operate on a shared `float*` data member which points to the
  underlying storage.

* There are also MxVector3/4Data classes, which inherit from Vector3/4,
  but add concrete storage for the Vector data rather than just an
  abstract data pointer.

* The same is true for MxMatrix, with there being an abstract and a
  concrete variant of it.

* Also improve reccmp.py register matching algorithm. It previously
  could not recognize an effective match when a swap had to take place
  between two registers used on the same line. It turns out this happens
  a lot in floating point math code so I adjusted the implementation to
  break the disassembly lines on spaces rather than just linebreaks
  allowing the existing effective match code to handle that case too.
