    [turbofan] Refactor the lowering of element/property accesses. · 1bce2790
    bmeurer authored
    Split the monster methods in JSNativeContextSpecialization into smaller
    ones, adding appropriate helpers. Improve the condition checking for
    strings and numbers using CheckString/CheckNumber when applicable. Also
    try to merge compatible PropertyAccessInfos, to avoid running into the
    polymorphic case whenever possible.
    
    Drive-by-fix: Don't try to resurrect dead nodes during LoadElimination.
    With the improve code generation for monomorphic loads, we seem to
    trigger the dead node resurrection.
