abstract-or-overapprox-vector hint

Concept

A performance hint implemented by rtlv/shiva that, for each entry of a memory field, either abstracts the entry (if it depends only on allowed dependencies) or overapproximates it otherwise. It is listed in Table 1 of the rtlv paper alongside other hints such as concretize, collect-garbage, and run-and-replace, and is intended to help control the growth of symbolic state during push-button verification of software on hardware.
