    cmake: Comment why we ignore the include-what-you-use return code · 44de6157

    The include-what-you-use tool always returns non-zero to indicate that
    it did not actually produce an object file as Clang would from the same
    command line.  Add a comment explaining that this is why we ignore its
    return code.  Also update our `pseudo_iwyu` test suite tool to always
    exit with an error too.
