commit 065fec99d6a27a72a0455c09e50fdffd1e736a3a

    StatProfile: Heap and blackhole sampling
    
    Based on Peter Wortmann's c01384a26d7c9d22d26a760470bdb6379a2913ee.
    Lacking a better idea, I follow Peter's lead and hackily lay claim to R9
    for funneling the attribution address to stg_gc_noregs.
    
    In addition I add support for profiling of blackhole wait events.
