  Log Message:
  -----------
  [OMPIRBuilder] CANCEL IF(FALSE) is still a cancellation point

>From OpenMP 4.0:

> When an if clause is present on a cancel construct and the if expression
> evaluates to false, the cancel construct does not activate cancellation.
> The cancellation point associated with the cancel construct is always
> encountered regardless of the value of the if expression.

This wording is retained unmodified in OpenMP 6.0.
