The MISS handler was being called when the receiver was a Smi, instead,
we should recognize the case and use the heap number map.

A FeedbackNexus is the combination of a feedback vector, a slot(s) in
the vector, along with methods to query and manipulate that information
in a type-correct way.
A CallIC will have a CallICNexus, a LoadIC a LoadICNexus, etc.,
reflecting the fact that different types of ICs configure their data
in unique ways.
This CL limits itself to introducing and using the nexus type only for
CallICs. A follow-up will use them for Load and KeyedLoadICs for the
case when the --vector-ics flag is turned on.
The notion of a Nexus is also embedded at the lowest level of the IC
class. This makes sense because more ICs should become vector-based
in the future.
