    X87: [Interpreter] Make dispatch table point to code entry instead of code objects. · eb89a753

      original commit message:
      Modifies Ignition to store code entry addresses in the dispatch table
      rather than code objects. This allows the interpreter to avoid
      calculating the code entry address from the code object on every
      dispatch and provides a ~5-7% performance improvement on Octane with
      Ignition.
    
      This change adds ArchOpcode::kArchTailCallAddress to TurboFan to enable
      tail call dispatch using these code addresses. It also adds a Dispatch
      linkage creator (distinct from the stub linkage type used previously) to
      allow targetting a code address target (which will diverge further from
      the stub linkage type when we remove the context machine register in
      Ignition).
