    [turbofan] Skip JSCallReducer and JSNativeContextSpecialization on asm.js. · 94b33165
    bmeurer authored
    For the old asm.js pipeline, there's no point in running either the
    JSCallReducer or the JSNativeContextSpecialization, as both will not
    kick in for any asm.js relevant code.
    
    So remove the kDeoptimizationEnabled flag from both of them and just
    run them on regular JavaScript only.
    
    Drive-by-fix: Slightly rearrange keyed access to String receivers in the
    JSNativeContextSpecialization::ReduceKeyedAccess method to access constant
    characters independent of the IC mode (as long as the constant index is
    within the range of the receiver).
