 * @brief Analyzer information
 *
 * Store various analysis information:
 * - checksum
 * - error messages
 * - whole program analysis data
 *
 * The information can be used for various purposes. It allows:
 * - 'make' - only analyze TUs that are changed and generate full report
 * - should be possible to add distributed analysis later
 * - multi-threaded whole program analysis
