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

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

Port 6fc97a19653e03a891d3cd397069d5a10b9ab325

Original commit message:
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.
