This pull request enhances CLE's capabilities to load DWARF information, particularly for Rust binaries. There will be a corresponding pull request in angr to take advantage of these changes to CLE. The current purpose of this pull request is to gather feedback on architecture/design. Note that the CLE side here is a bit more well tested than the angr side.
Summary of changes:
EnumerationType,SubroutineType,SubprogramType,ConstType,VariantTypeas subclasses of VariableType. Adds functions to load these classes from DWARF information.Subprogram, which inherited fromLexicalBlock. Figure out ifSubprogramTypeshould remain separate from this class.See also: angr/angr#5857
