[Bug 8051] Sims 2 demo exits prematurely

some hacks that allow the demo to start

three problems identified so far:

1) as mentioned in comment #18 it tries to set 1024 vertex shader constants.
d3d9 allows up to 8192 constants in software vertex processing mode so that
request should be valid. As it seems there isn't really a "software processing
mode" in wined3d (right?), so for now just ignore any constants beyond the ones
that wined3d and the hw supports. Here it is just used to initially set these
constants to zero so it shouldn't cause too much trouble.

2) next problem is that GetDepthStencilSurface() fails with D3DERR_NOTFOUND.
What happens is:
CreateDevice() called with AutoDepthStencil=true
SetDepthStencil(NULL)
Reset() called with AutoDepthStencil=true
GetDepthStencilSurface() is expected to return something.
Not sure what the proper fix is here. Just reassign the stencilBufferTarget to
existing auto_depth_stencil_buffer as done in the patch or create a new one ?

3) segfault because of missing export Direct3DShaderValidatorCreate9().
Sadly this function seems to be completely undocumented :(.

Demo is still completely unusable though because of rendering errors(most
notably the sim isn't rendered at all).
