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.
