i965: Use ~0 to represent true on all generations.
Jason realized that we could fix the result of the CMP instruction on
Gen <= 5 by doing -(result & 1). Also do the resolves in the vec4
backend before use, rather than when the bool was created. The FS does
this and it saves some unnecessary resolves.
On Ironlake:
total instructions in shared programs: 4289762 -> 4287277 (-0.06%)
instructions in affected programs: 619430 -> 616945 (-0.40%)
