    Original Commit Message:
      This CL adds a first implementation of Liftoff, the new wasm baseline
      compiler, for x64 and ia32. It currently supports the most important
      i32 instructions and control instructions. Whenever it encounters an
      instruction it does not support yet, it aborts.
      In a subsequent CL, Liftoff will be called from the
      WasmCompilationUnit, falling back to Turbofan compilation if the
      baseline compiler bails out.
