nir: Add variants of some of the comparison simplifications.

We end up with these from TGSI-to-NIR because the pass generating the
comparisons doesn't know if the arg is actually a bool input or not.  vc4
results:

total instructions in shared programs: 41801 -> 41508 (-0.70%)
instructions in affected programs:     4253 -> 3960 (-6.89%)
