Reviewers: Jakob,
Message:
Hi Jakob, thanks for the help on this issue. Here is the fix we discussed.
I was
able to add --nocall-ic support too.

Description:
Reland "Customized support for feedback on calls to Array." and follow-up
fixes.
Comparing one CallIC::State to another was not done correctly, leading to a
failure to patch a CallIC when transitioning from monomorphic Array to
megamorphic.
