X87: [compiler] Sanitize entry points to LookupSlot access.

  port 4ff159bd28be36a39a1f8416cdf8fccafd3c2f95(r33880)

  original commit message:
  Add dedicated %LoadLookupSlot, %LoadLookupSlotInsideTypeof,
  %LoadLookupSlotForCall, %StoreLookupSlot_Sloppy and
  %StoreLookupSlot_Strict runtime entry points and use them
  appropriately in the various compilers. This way we can
  finally drop the machine operators from the JS graph level
  completely in TurboFan.

  Also drop the funky JSLoadDynamic operator from TurboFan,
  which was by now just a small wrapper around the runtime
  call to %LoadLookupSlot.
