marked as 'not executed'.
In the current coverage mapping implementation, we terminate the current region
and start a zero region when we hit a nonreturn function. However, for logical OR,
the second operand is not executed if the first operand evaluates to true. If the
nonreturn function is called in the right side of logical OR and the left side of
logical OR is TRUE, we should not start a zero `GapRegionCounter`. This will also
apply to `VisitAbstractConditionalOperator`.
