* ``MAX_PREDICATE_REGISTERS``: indicates the number of predicate registers
available. Predicate register may be set as a side-effect of ALU
instructions to indicate less than, greater than or equal to zero.
Later instructions can use a predicate register to control writing to
each channel of destination registers. NOTE: predicate registers have
not been fully implemented in Gallium at this time. See the
GL_NV_fragment_program extension for more info (look for "condition codes").
