      Remove weak-list of optimized JS functions. · f0acede9
      Juliana Franco authored
      This CL removes the weak-list of JS functions from the context
      and all the code that iterares over it. This list was being used
      mainly during deoptimization (for code unlinking) and during
      garbage collection. Removing it will improve performance of
      programs that create many closures and trigger many scavenge GC
      cycles.
      
      No extra work is required during garbage collection. However,
      given that we no longer unlink code from JS functions during
      deoptimization, we leave it as it is, and on its next activation
      we check whether the mark_for_deoptimization bit of that code is
      set, and if it is, than we unlink it and jump to lazy compiled
      code. This check happens in the prologue of every code object.
       
      We needed to change/remove the cctests that used to check
      something on this list.
       
      Working in x64, ia32, arm64, arm, mips64 and mips.
