Clemens Backes 156b240954 [wasm][test] Cleanup macros 
Some macros are redundant or unused.
- WASM_RETURN1 is identical to WASM_RETURN.
- WASM_RETURNN has an unused {count} parameter, and is otherwise
  identical to WASM_RETURN.
- WASM_IFB is identical to WASM_IF.
- WASM_CASE and WASM_CASE_BR are unused.
- WASM_BR_TABLEV is unused.
