wined3d: Get rid of pshader_gen_output_modifier_line. 

Use shader_arb_add_instruction_modifiers instead. This avoids calling the
fixup function from each single instruction handler to handle shifts. It does
not yet get rid of the modifier handler in each instruction because we don't
want a separate line if we can just append _SAT to the instruction name.
