[wasm] Binary 11: br_table takes a value. [wasm] Binary 11: Add implicit blocks to if arms. [wasm] Binary 11: Add arities to call, return, and breaks [wasm] Binary 11: Add experimental version. This CL changes the encoder, decoder, and tests to use a postorder encoding of the AST, which is more efficient in decode time and space.
