We add two records in sil_block to specify a Vtable and its entry list. Two records are also added in sil_index_block for mapping from name to ID and from ID to bit offset. Two functions are added to SerializedSILLoader: to look up a specific VTable given the class name or to deserialize all VTables in all SILModules. The latter is mostly used for testing. We serialize a VTable if the class is fragile and deserialize it via SerializedSILLoader::lookupVTable. Swift SVN r9746
