r600g: add support for primitive id without geom shader (v2)
GLSL 1.50 specifies a fragment shader may have a primitive id
input without a geometry shader present.
On r600 hw there is a special GS scenario for this, you have
to enable GS_SCENARIO_A and pass the primitive id through
the vertex shader which operates in GS_A mode.
This is a first pass attempt at this, and passes the piglit
tests that test for this.
v1.1: clean up debug print + no need to assign
key value to setup output.
v2: add r600 support
