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.
