i965/fp: Emit discard jumps.

This should improve the performance of any shaders using the KIL
instruction.  I'm a bit surprised we missed this.

Unfortunately, I have not been able to measure any performance
improvements from this patch.  It does make ARB_fragment_program
behave similarly to GLSL code.
