    mesa: Enable simultaneous queries on different streams.
    
    It should be possible to query the number of primitives written to each
    individual stream by a geometry shader in a single draw call. For that
    we need to have up to MAX_VERTEX_STREAM separate query objects.

    i965: Implement GL_PRIMITIVES_GENERATED with non-zero streams.
    
    So far we have been using CL_INVOCATION_COUNT to resolve this query but this
    is no good with streams, as only stream 0 reaches the clipping stage. Instead
    we will use SO_PRIM_STORAGE_NEEDED which can keep track of the primitives sent
    to each individual stream.
    
    Since SO_PRIM_STORAGE_NEEDED is related to the SOL stage and according to
    ARB_transform_feedback3 we need to be able to query primitives generated in
    each stream whether transform feedback is active or not what we do is to
    enable the SOL unit even if transform feedback is not active but disable all
    output buffers in that case. This effectively disables transform feedback
    but permits activation of statistics enabling SO_PRIM_STORAGE_NEEDED even
    when transform feedback is not active.

    i965/gs: Set number of control data bits for stream mode.

    bits per vertex for the StreamID. If the shader is not using streams then
    we don't need control data bits.

    glsl: Store info about geometry shaders that emit vertices to non-zero streams.
    
    On Intel hardware when a geometry shader outputs GL_POINTS primitives we
    only need to emit vertex control bits if it emits vertices to non-zero
    streams, so use a flag to track this.
    
    This flag will be set to TRUE when a geometry shader calls EmitStreamVertex()
    or EndStreamPrimitive() with a non-zero stream parameter in a later patch.
