Think about hierarchy of intrinsics.

Think about unifying regionId and symbolicMapDescriptor

Extend heap with
SymbolicMapcopySymbolicMapIndexRangeoperation for maps with anIndexkey that acts like amemcpymergeSymbolicMapthat merge one map into another (key union, values overwrite when intersect)SymbolicMaphasAllocatedandInputregion ids, which are parametrized withSymbolicMapDescriptor. This representaion allow extensibility because when a map with a new key sort is required we only need to define a new descriptor.Intrinsics
ObjectMap--- map with object (reference) keys. Currently, use reference equality and act like ajava.util.IdentityHashMapList--- list, dynamic array, vector, etc.Engine--- allows usvm state manipulation:assume,makeSymbolic
