Sorry for being slow here.  I was poking at trying to write
generated_tests support to build more tests, and ended up down a
rathole.  Given how few extensions to GLSL I see, I'm not sure it's
worth the effort to generate for just this one time, instead of
hand-writing.

I'd be happy to see a few values tested for each function in the style
of, e.g.
generated_tests/spec/glsl-1.30/compiler/built-in-functions/op-complement-int.vert
instead of round-tripping through both functions for the test.
