glsl-1.10: Add tests for condition on saturated value
On Intel GPUs these tests produce code like
...
add.sat dest src0 scr1
cmp.xx null src0 src2
...where src1 == -src2.
Because saturation comes before applying conditional modifier, it
should not be propagated, unless conditional modifier (.xx) is .g or
.le.
