X87: Retry "Use a WeakCell in the CallIC type vector."

port 6fc97a19653e03a891d3cd397069d5a10b9ab325 (r26420)

original commit message:

  Retry "Use a WeakCell in the CallIC type vector."

  The first try failed because I needed to make a better distinction
  between clearing ICs according to policy at GC time or unconditional
  clearing (say, via %ClearFunctionTypeFeedback).

  It was also blocked by an issue in super constructor calls.
  This fix (https://codereview.chromium.org/892113002/) needs to land
  before checking in this CL.
