mesa: avoid generating constant vertex attributes in fixedfunc programs
Keep track of enabled/active vertex attributes. Keep track of potential vertex program outputs. When generating fragment program, replace references to fragment attributes which are effectively non-varying and non-computed passthrough attributes with references to the new CURRENT_ATTRIB tracked state value. Only downside is slight ugliness in VBO code where we need to validate state twice in succession.
