[commit: ghc] ghc-lwc2: Scheduler: scheduleThreadOnFreeCap updated such it only checks whether the capability hasn't already been picked up by another user-level scheduler. In particular, we no longer consider run queue being non-empty, a blocked foreign call on this capability or outstanding messages to be the reasons for not picking up a capability. (6f07516)

    Scheduler: scheduleThreadOnFreeCap updated such it only checks whether
    the capability hasn't already been picked up by another user-level
    scheduler. In particular, we no longer consider run queue being
    non-empty, a blocked foreign call on this capability or outstanding
    messages to be the reasons for not picking up a capability.
    
    Benchmarks: Added TMVar implementations. Weeding through IOManager
    bugs.
