[PATCH v4 1/4] vkd3d-shader: Treat the HLSL case specially in vkd3d_shader_scan().

[Giovanni Mascellani]

From: Giovanni Mascellani

The other cases are similar and common code can be refactored.
Ideally the HLSL parser will eventually fit the same model, but that
will require more extensive work.
