tgsi: remove special-case code for fragment position
Since the origin_lower_left / pixel_center_origin changes, we need
to use the fragcoord info that's set up in setup_fragcoord_coeff().
The code in exec_declaration() was clobbering the the interpolated
fragment position.
Fixes progs/glsl/fragcoord.c demo.
