/**
  This macro uses the framework assertion logic to check whether a function call
  triggers an ASSERT() condition.  The BaseLib SetJump()/LongJump() services
  are used to establish a safe return point when an ASSERT() is triggered.
  If an ASSERT() is triggered, unit test execution continues and Status is set
  to UNIT_TEST_PASSED.  Otherwise, a unit test case failure is raised and
  Status is set to UNIT_TEST_ERROR_TEST_FAILED.

  If ASSERT() macros are disabled, then the test case is skipped and a warning
  message is added to the unit test log.  Status is set to UNIT_TEST_SKIPPED.

  @param[in]  FunctionCall  Function call that is expected to trigger ASSERT().
  @param[out] Status        Pointer to a UNIT_TEST_STATUS return value.  This
                            is an optional parameter that may be NULL.
