Cleanups for test cases:

- Allow a code-generation target of `NONE` in order to suppress ordinary output in test cases where we don't care about the actual output (just pass/fail result)

- Add explicit `location` layout qualifiers to intermediate vertex-to-fragment variables in GLSL test cases for rendering, to work around apparent Intel driver bugs.
