    [compiler] Enable feedback collection in generic lowering · e63bae12
    Jakob Gruber authored
    Turbofan now has support for generating generic code in two variants,
    with and without feedback collection. Currently, feedback is collected
    only for some load and store operators (historical reasons).
    
    This CL enables feedback collection for (almost) all operators by
    default. The exception in the default TF configuration are call and
    construct variants (see also https://crrev.com/c/2276042). In NCI mode,
    all operators collect feedback.
    
    Regression have looked acceptable in our benchmarks so far. This is an
    experiment to see impact on real world. If successful, the
    non-collecting variants can be removed.
