    glsl_to_tgsi: implement ir_unop_logic_not using 1-x

    Since our logic values are 0.0 (false) and 1.0 (true), 1.0 - x accurately
    implements logical not.

    This is a port of commit 6ad08989d7c1 to glsl_to_tgsi.

This is a r300 compiler bug.  Flow control doesn't work very well for vertex shaders at the moment.  I have been slowly working on fixing this, but I'm not
quite done yet.
