[sldev] SSE2 on MSVC

[Nicholaz Beresford]

Dunno if the code bit below makes any sense (I haven't got
much idea what SSE2 is, despite having read it on Wikipedia),
but what do you think?

	//
	// enable MSFT SSE2 extensions
	//
	CProcessor cproc;
	const ProcessorInfo *pinfo= cproc.GetCPUInfo();
	int sse2= FALSE;
	if (pinfo->_Ext.SSE2_StreamingSIMD2_Extensions) {
		// http://msdn2.microsoft.com/en-us/library/bthd138d(VS.80).aspx
		sse2= _set_SSE2_enable(TRUE);
	}
	llinfos << "running with" << (!sse2 ? "out" : "" ) << " _set_sse2_enabled " << llendl;
