Non square matrices related fixes

- Implemented proper VariableRegisterCount (we were using row
  count instead of column count to get the number of registers)
  and VariableRegisterSize.
- Matrix to matrix copies now clear the correct rows of the
  destination matrix when needed
- Added registerSize helper function to type to help clarify
  this for matrices.
- Added missing member initializations in TType constructor
