    [nci] Don't lower feedback-collecting operators · a8a1776e
    Jakob Gruber authored
    Feedback collection is currently implemented only for JS operators in
    generic lowering. Missing feedback collection results in soft-deopts
    immediately after tiering up to TF from NCI code.
    
    In this CL we disable two large classes of such problematic lowerings
    for NCI code, type hint lowering and typed lowering.
