clamp regcount for D3DXPC_MATRIX_COLUMNS.

After some discussion and debugging, the result is the following:

The issue is that currently the regcount in the ID3DXConstantTable is not
clamped for D3DXPC_MATRIX_COLUMNS. Thus some values for the next shader
variable may be overwritten in some cases.

The patch as is works, but it needs a nice test case...
