Texturing instructions can't read from constant sources, however this can work when the constant was transformed to constant swizzles and hence RC_FILE_NONE. Prevents a regression in single Unigine Tropics shader that uses constant (0.5,0.5) as a TEX coordinate in a next patch. We now convert to constant swizzles twice, first when translating from TGSI and than in constant folding. If we disable the first conversion rc_transform_tex will emit a mov from constant to temporary. With this patch, copy propagate will clean it up later.
