    Also added known-good mechanism to fetch latest validated spirv-tools.
    Also added -Od and -Os to disable optimizer and optimize for size.
    Fetching spirv-tools is optional for both glsl and hlsl. Legalization
    of hlsl is done by default if spirv-opt is present at cmake time.
    Optimization for glsl is currently done through the option -Os.
    Legalization testing is currently only done on four existing shaders.
    A separate baseLegalResults directory holds those results. All previous
    testing is done with the optimizer disabled.
