Source maps?

[leonhma]

It would be great to have source map support. This would involve generating a sourcemap (preferably including sources) from llvm dwarfdump info via this cli tool, or via wasm-pack (drager/wasm-pack#824), and then adding this sourcemap to the build output and a reference in the wasm binary (see this).

Probably now wasm2map can be used.
