This matches the existing export-name attribute but exports that symbol
but its llvm symbol name.  This corresponds directly to the existing
WASM_SYMBOL_EXPORTED symbol flag.

This allows the existing emscripgten macro `EMSCERIPTEN_KEEPALIVE` to be
implemented in terms of this attribute rather then the current
workaround which uses the `used` attribute.
