    [wasm] Use isorecursive canonical types for call_indirect · 4f0ef8c3
    Manos Koukoutos authored
    Currently, we canonicalize types for call_indirect by looking in the
    current module for a signature of the same shape. This is not enough
    as of wasm-gc. Instead, the canonical identifier representing a type
    has to be computed via isorecursive canonicalization.
    This change is implemented behind a flag for now.
    Future work: Also integrate export wrappers with isorecursive
    canonical types. We need to store wrappers in instance-independent
    storage.
    
    Drive-by:
    - Always emit type check for call_indirect. We did not emit a check
      only when typed-function-references was enabled, but not gc. This
      is not something that will be possible long-term.
    - Fix some wasm cctests.
