[PATCH] D37101: [clangd] [WIP] Add support for snippet completions

[Raoul Wols via Phabricator via cfe-commits]

rwols added a comment.

After digging into VSCode, I now think that presenting snippets is the wrong way forward, and I believe the right way is to implement the `signatureHelpProvider` protocol for method/function parameters. See: https://github.com/Microsoft/vscode-docs/blob/master/docs/extensionAPI/language-support.md#help-with-function-and-method-signatures.

I'll update this diff accordingly.
