The mediump lowering tests are important for poking at the lowering pass
behavior, since you can't really assert the behavior in any given driver,
given that the GLSL spec allows any mediump op to be done in highp.
But, in hacking on mediump lowering, I wanted several things that the old
test couldn't do:
- Be able to assert about the actual NIR code we expect to generate for a
hypothetical driver (important if other compiler stages might do invalid
transformations like eliminating highp temps, or if we were to move the
lowering after GLSL IR)
- Run faster (gtest unit tests rather than python forking off the standalone
glsl compiler per testcase).
- Express expectations with a lot less escaping of typical syntax.
- High-quality logs for displaying failures.
This new test does all of that, I think, though I haven't converted all of
the unit tests over yet. In converting, I dropped some of the
combinatorial explosion for float/int variations, instead only doing so
when it gets at some different code path (default precision flags). I've
also included some new tests I wrote in the process of writing my proposed
gl_nir mediump lowering.
Even if the conversion isn't complete, getting these tests to run faster
is probably a good idea on its own, for anyone iterating running Mesa's
unit tests (80 tests in 25ms, compared to 109 tests in 1.5s!).

bitCount is still special in that our lowering would try to demote its arg
based on the precision of its output, and it shouldn't do that. But the
