    [turbofan] Separate typed optimizations from JSTypedLowering. · f154c75a
    bmeurer authored
    Introduce a new TypedOptimization reducer that contains the type
    based optimization reduction steps, which are not (directly)
    related to lowering JavaScript operators based on types (which is
    what JSTypedLowering is supposed to do).
    
    This also addresses a chicken-and-egg problem that we see in the
    Octane/Mandreel benchmark where type based constant folding isn't
    applied to the numeric comparison operators introduced by the
    JSTypedLowering itself, and thus gives up to 10% speedup for the
    benchmark.
