    Add the GC_GLOBAL_SYNC event marking that all caps are stopped for GC · c294d95d

    Quoting design rationale by dcoutts: The event indicates that we're doing
    a stop-the-world GC and all other HECs should be between their GC_START
    and GC_END events at that moment. We don't want to use GC_STATS_GHC
    for that, because GC_STATS_GHC is for extra GHC-specific info,
    not something we have to rely on to be able to match the GC pauses
    across HECs to a particular global GC.
