Manos Koukoutos 0a69768a4e [wasm-gc] Implement ref.as_non_null, optimize struct instructions. ... Implement the instruction ref.as_non_null, as per the wasm gc extension. Changes: - Add the respective wasm opcode, move some asmjs opcodes around. - Add a new type of wasm trap, IllegalCast. - Modify wasm decoding and compilation pipeline. - Add a minimal test. - In wasm-compiler, generalize Unreachable to Trap. - Optimize struct.get and struct.set for non-null types.
