wasm_pass_by_reference passes every aggregate indirectly, while
wasm_return_in_memory returns ordinary records directly. The assembler
signature printer independently treats records as pointers. This produces
incompatible parameter/result types and can emit a result from a no-result
function.
Use one shared Basic C ABI classifier for argument lowering, return
lowering, and signature emission.
