While the opengl state tracker uses ADDR in this way, it is not in any way
required by TGSI or gallium that this be the case. ADDR registers can be used
however you want, they're just registers like any other, except that they can
be used for indirect indexing into TEMP and CONST registers (perhaps IN and OUT
as well, not sure), and with ARB_gs5, into SAMP as well.
