* cleanups * ast.nim: cleanups * IC: no more sym.tab field, stored externally in the module graph * nimble compiles again * rodfiles: store bitwidth of integers and the endianness in the cookie because we serialize 'int' directly * rodfiles: added compilerproc and export sections * rodfiles: added all the missing sections * rodfiles: track the missing information * IC: architecture for lazy loading of proc bodies * make tests green again * completed the lazy loading of proc bodies * symbol lookup integration, part 1 * symbol lookup integration, part 2 * symbol lookup integration, part 3 * make tcompilerapi work again * rodfiles: fixed config change handling
