Short patchset to go some way towards improving the handling of NIR control flow graphs in vc4.
Whilst in no way completely addressing the known issues this improves piglit output, provides better internal handlers for loop and function nir_cf_node types and creates a cleaner base upon which to build. Fixes the following piglit tests: - shaders/complex-loop-analysis-bug - shaders/glsl-fs-discard-04 Converts the following piglit tests from crash to fail: - shaders/glsl-fs-continue-inside-do-while - shaders/glsl-fs-loop - shaders/glsl-fs-loop-continue - shaders/glsl-fs-loop-nested - shaders/glsl-texcoord-array - shaders/glsl-vs-continue-inside-do-while - shaders/glsl-vs-loop - shaders/glsl-vs-loop-continue - shaders/glsl-vs-loop-nested No piglit regressions. Importantly, the specific piglit fixes reported were from a debug build of Mesa. At present there are known vc4 problems exposed by piglit with release builds. I hope to work on resolving these shortly. Nonetheless a full piglit run was also done with release builds and I confirm no regressions were seen.
