See comments for details. This allows the piglit
ext_framebuffer_multisample-point-smooth test to pass.
Also, test the pipe_rasterizer_state::point_quad_rasterization field
to see if sprite point rasterization is needed because it's possible
for no sprite_coord_enable bits to be set when drawing sprites.
Finally, remove old, stale comments.

If real MSAA is not available, we only support 1 sample/pixel. In that
case, we must not declare MSAA resources or emit MSAA opcodes. Do that
by checking the sample count.
Fixes several piglit MSAA tests, such as
arb_texture_multisample-sample-depth (when the hard-coded sample count
of 4 is fixed in that test).

Currently we have one function to get format capabailities and
we convert DX10 devcaps back to DX9. This can be confusing.
Going forward we will have a separate function for dealing with dx formats.
This patch also fixes the depth stencil devcap. Instead of hardcoding
the capabilities for the depth stencil formats, we will inquire the
device for the capabilities. Note: we will still need to explicity set
the SVGA3D_DXFMT_SHADER_SAMPLE bit for SVGA3D_R32_FLOAT_X8X24 and
SVGA3D_R24_UNORM_X8 since this bit is not advertised but supported
by the device.

Currently, the starting index for system values is assigned to

But the tgsi index might be different from the actual assigned index, hence

With this patch, the shader linker keeps track of the highest index of the
translated input registers, and the next index will be used for the
starting index for system values.
