Revert "Only process cross traffic simulation if added."

This reverts commit 491d29448e4a0f501f1ea115b218ed5250fbd3dc.

Reason for revert: Breaks internal iOS waterfall

Original change's description:
> Only process cross traffic simulation if added.
> 
> This avoids extra processing overhead when there's no cross traffic
> simulation active. To allow the use of SendTask, GlobalTimeController
> is adjusted so it always overrides yield behavior.
> 
> Also adding sequence checkers to protect against races on
> read access.
