test with 5 paramaters

Ok, here's another attempt, one day this bug will be fixed ;)

Test attached is:
#include <d3d8.h>
#include "wine/test.h"

static HRESULT (WINAPI *ValidateVertexShader)(LPVOID,int,LONG,int,LPVOID);

static void test_ValidateVertexShader(void)
{
HRESULT ret;
ret=ValidateVertexShader(0,0,0,1,0);
ok(ret==E_FAIL,"ValidateVertexShader returned %lx but expected E_FAIL\n",ret);
}

START_TEST(d3d8_main)
{
    HMODULE d3d8_handle = LoadLibraryA( "d3d8.dll" );
    ValidateVertexShader = (void*)GetProcAddress (d3d8_handle,
"ValidateVertexShader" );
    test_ValidateVertexShader();
}

I'm just passing dumb zero's to the function, except the 4th parameter, which
takes a 1. The 1 is for example passed by
http://www.codesampler.com/source/dx8_vs11_shader_simple.zip
This test fails in wine (run 'wine d3d8_crosstest5.exe d3d8_main')

However, you can just call ValidateVertexShader from a native d3d8.dll in wine,
so WINEDLLOVERRIDES="d3d8=n" wine d3d8_crosstest.exe d3d8_main succeeds just
fine.

I'll attach hereafter the test based on _current_ "implementation" of
ValidatevertexShader, and that fails with native d3d8.dll
