Update wasm app build scripts for wasi-sdk-12 and refine interpreter (#481)
Update wasm app build scripts for wasi-sdk-12.0: add --export=__main_argc_argv, remove --no-threads
Lookup function with name "__main_argc_argv" as main function besides "main"
Change module_malloc to runtime_malloc in wasi native lib
Refine classic interpreter op_block and op_br_table
Refine faster interpreter op_br_table
