    Introduce FeedbackNexus for vector-based ics. · a2e21393
    mvstanton@chromium.org authored
    A FeedbackNexus is the combination of a feedback vector, a slot(s) in
    the vector, along with methods to query and manipulate that information
    in a type-correct way.
    
    A CallIC will have a CallICNexus, a LoadIC a LoadICNexus, etc.,
    reflecting the fact that different types of ICs configure their data
    in unique ways.
    
    This CL limits itself to introducing and using the nexus type only for
    CallICs. A follow-up will use them for Load and KeyedLoadICs for the
    case when the --vector-ics flag is turned on.
    
    The notion of a Nexus is also embedded at the lowest level of the IC
    class. This makes sense because more ICs should become vector-based
    in the future.
