ARB prog parser: use _mesa_add_unnamed_constant() to use fewer constant slots
This function will search the constant parameters in an effort to re-use constant slots. For example, {1,2,3,4} and {4,1,1,2} can be stored in one constant slot and accessed with different swizzles. The swizzle info must be propogated though the parsing code in a few places. Fixes Piglit "vpfp-generic tests/shaders/generic/big-param.vpfp" failure.
