mesa: new _mesa_remove_varying_reads() function
We'll apply this function to GLSL vertex programs. In GLSL it's legal to read and write varying (output) vars in a vertex shader. But reading from an output register isn't supported by all hardware. This routine examines the vertex program for that condition and rewrites it to use temporary registers where needed.
