    Event tracing: put the capability in the block marker, omit it from the events · e459b0d1

    This makes events smaller and tracing quicker, and speeds up reading
    and sorting the trace file.
    
    HEADS UP: this changes the format of event log files.  Corresponding
    changes to the ghc-events package are required (and will be pushed
    soon).  Normally we would make backwards-compatible changes, but this
    changes the format of every event (to remove the capability) so I'm
    breaking the rules this time.  This will be the only time we can do
    this, since the format becomes public in 6.12.1.
