[PATCH] D150803: [WebAssembly] Add a new `wasm_async` clang attribute for marking async functions.

[Brendan Dahl via Phabricator via cfe-commits]

brendandahl added a comment.

After some feedback, a few people have indicated they'd like to do something similar to this, but for their own attributes. I've changed to a more generic attribute that allows arbitrary strings. Now a custom section will be created for each unique attribute.
