Add core abstractions for identifying program entities across compilation and link unit boundaries in the Scalable Static Analysis Framework (SSAF). Introduces three key components: - BuildNamespace: Represents build artifacts (compilation units, link units) - EntityName: Globally unique entity identifiers across compilation boundaries - AST mapping: Functions to map Clang AST declarations to EntityNames Entity identification uses Unified Symbol Resolution (USR) as the underlying mechanism, with extensions for sub-entities (parameters, return values) via suffixes. The abstraction allows whole-program analysis by providing stable identifiers that persist across separately compiled translation units.
