Roundtrip (export/reimport) class declarations The remapping was previously implemented using name_scopes, which aren't created for class declarations, only definitions - causing the reimport to import a fresh copy of the type that mismatched with the original (as seen in the test baseline). By changing the mapping to use the reverse part of the clang_decls mapping this should generalize better (& we probably should further migrate to that mapping). Though it did trip over some issue with exactly which instruction is used as the key in the clang_decls map - this change moves towards standardizing on the first decl id of the class as its map key.
