commit 6a70f2060dd48ae61ed6cc5d613befa32416342b

    fix AMD64 invalid encoding of events with umask revision constraints
    
    The encoding was not picking up the right umask, e.g., for
    AMD K8 PROBE:ALL for instance. There is a ALL encoding up till
    version C, then another one from D-G.
    
    That was coming from a bogus amd64_umask_valid() and also because
    both pfm_amd64_get_event_info() and pfm_amd64_get_event_attr_info()
    were relying on attribute indexes being contiguous. They are not
    because some umask may be skipped.
    
    The common code was also at fault because it was not using the
    ainfo.idx to encode the index of the attribute.
    
    The pfmlib_sanitize_event() routine must look at the attribute
    type to find duplicates.  Two attributes are duplicates if they
    have the same attr index AND the same type. On AMD64, due to
    the gaps in umasks, a umask and a modifier may have the same
    index.
