    [turbofan] Decouple inlining and native context specialization. · 9b14e5bb
    bmeurer authored
    Retrieve the native context/global object from the Node being
    specialized in the JSNativeContextSpecialization and the
    JSGlobalObjectSpecialization classes. For this we introduce two
    new methods NodeProperties::GetSpecializationNativeContext and
    NodeProperties::GetSpecializationGlobalObject, which walk up
    the context chain and might in the end take the native context
    from the outermost activation (if native context specialization
    is enabled). This allows us to run the native context specialization
    pass as part of the inlining phase without hacking some of that into
    the JSInliner.
    
    Also refactor the NodeProperties::GetSpecializationContext method
    that was previously local to the JSContextSpecialization.
    
    Also refactor two other oddities in JSNativeContextSpecialization.
