    [wasm-gc][bug] Fix signature canonicalization · 4d9d8518
    Manos Koukoutos authored
    We used not to emit canonical indexes for arrays and structs into
    WasmModule::signature_ids, which resulted in signature_ids not referring
    to the correct type indices in a WasmModule.
    
    Changes:
    - Rename signature_ids to canonical_type_ids.
    - Emit trivial canonical type ids for structs and arrays.
    - Add a test to catch the existing bug.
    - Improve DCHECKs for module type accessors.
