  *
  * @brief These unit tests check compiler builtins.
  *
  * Explicitly test the 64-bit integer division and modulo operations.  They are
  * essential for the timekeeping services.  On most 32-bit targets, they need a
  * software implementation.
  *
  * This test case performs the following actions:
  *
  * - Check the return value of __builtin_clz() for a sample set of inputs.
  *
  * - Check the return value of __builtin_clzll() for a sample set of inputs.
  *
  * - Check the return value of __builtin_ctz() for a sample set of inputs.
  *
  * - Check the return value of __builtin_ctzll() for a sample set of inputs.
  *
  * - Check the return value of __builtin_ffs() for a sample set of inputs.
  *
  * - Check the return value of __builtin_ffsll() for a sample set of inputs.
  *
  * - Check the return value of __builtin_parity() for a sample set of inputs.
  *
  * - Check the return value of __builtin_parityll() for a sample set of inputs.
  *
  * - Check the return value of __builtin_popcount() for a sample set of inputs.
  *
  * - Check the return value of __builtin_popcountll() for a sample set of
  *   inputs.
  *
  * - Check the return value of __builtin_bswap32() for a sample set of inputs.
  *
  * - Check the return value of __builtin_bswap64() for a sample set of inputs.
  *
  * - Check signed 64-bit comparisons for a sample set of values.
  *
  * - Check unsigned 64-bit comparisons for a sample set of values.
  *
  * - Check signed 64-bit arithmetic left shift for a sample set of values.
  *
  * - Check signed 64-bit arithmetic right shift for a sample set of values.
  *
  * - Check unsigned 64-bit logical right shift for a sample set of values.
  *
  * - Check signed 64-bit multiplication for a sample set of values.
  *
  * - Check signed 64-bit negation for a sample set of values.
  *
  * - Check signed 64-bit divisions for a sample set of values.
  *
  * - Check unsigned 64-bit divisions for a sample set of values.
  *
  * - Check signed 64-bit modulo operations for a sample set of values.
  *
  * - Check unsigned 64-bit modulo operations for a sample set of values.
