    [wasm] Complete element segment features for reftypes/typed-funcref · 37579df7
    Manos Koukoutos authored
    Main changes:
    - Allow global.get in elements segments with expressions-as-elements.
    - Allow element segments with types other than funcref.
    
    Detailed changes:
    - Move WasmInitExpr to its own file. Add stream opearator << support.
    - Simplify type of PrintCollection.
    - Make WasmElemSegment use an array of WasmInitExpr's over the previous
      ad-hoc implementation. Move null_index to WasmModuleBuilder.
    - Refactor consume_element_segment_header. Make it return a
      WasmElemSegment.
    - Refactor consume_element_expr. Make it return a WasmInitExpr.
    - Refactor DecodeElementSection. Make it invoke
      consume_element_segment_header, then populate its element array.
    - Update module-instantiate.cc to handle global.get elements.
    - Fix bug in wasm-objects.cc where the wrong type index was passed into
      module()->has_signature()
    - Adapt and add tests.
