This folds the menagerie of various configuration option arguments to `macawExtensions` into the `MemModelConfig` data type. The advantage to doing this is that is will make it easier to extend the memory model configuration options in the future without needlessly foisting breaking changes on all `macaw-symbolic` users. Unfortunately, it does require a breaking change to get to this point, but the migration path is straightforward for existing code. I have included this migration story in the `macaw-symbolic` changelog. |

Macaw Refinement Libary
The refinement library provides supplemental functionality for discovery of elements that macaw-symbolic is not able to discover via pattern matching. This library will use crucible symbolic analysis to attempt to determine elements that could not be identified by macaw-symbolic. The identification provided by macaw-symbolic is incomplete, and so is the identification by this macaw-refinement, but macaw-refinement attempts to additionally "refine" the analysis to achieve even more information which can then be provided back to the macaw analysis.
-
Terminator effects for incomplete blocks. For example, the target IP address by symbolic evaluation (e.g. of jump tables). If the current block does not provide sufficient information to symbolically identify the target, previous blocks can be added to the analysis (back to the entry block or a loop point).
-
Argument liveness (determining which registers and memory locations are used/live by a block allows determination of ABI compliance (for transformations) and specific block requirements (which currently start with a full register state and blank memory).
-
Call graphs. Determination of targets of call instructions that cannot be identified by pattern matching via symbolic evaluation, using techniques similar to those for identifying incomplete blocks.
