    [turbofan] Optimize certain chains of Branch into a Switch. · acd9c46c
    bmeurer authored
    This adds a new ControlFlowOptimizer that - for now - recognizes chains
    of Branches generated by the SwitchBuilder for a subset of javascript
    switches into Switch nodes. Those Switch nodes are then lowered to
    either table or lookup switches.
    
    Also rename Case to IfValue (and introduce IfDefault) for consistency.
