Detailed Description

Concrete subclass of svalue representing a mapping of bit-ranges
to svalues, analogous to a cluster within the store.

This is for use in places where we want to represent a store-like
mapping, but are required to use an svalue, such as when handling
compound assignments and compound return values.

All keys within the underlying binding_map are required to be concrete,
not symbolic.

Instances of this class shouldn't be bound as-is into the store;
instead they should be unpacked.  Similarly, they should not be
nested.
