wasm_import_module
This is now stabilized! Also tweak usage of it to the stable version.
This has been stabilized on nightly as `#[link_section]`, so no need for an unstable attribute any more. Yay!
wasm2asm
This commit adds an example of executing the `wasm2asm` tool to generate asm.js output instead of WebAssembly. This is often useful when supporting older browsers, such as IE 11, that doesn't have native support for WebAssembly.
