[PATCH] D104601: [Preprocessor] Implement -fnormalize-whitespace.

[Michael Kruse via Phabricator via cfe-commits]

Meinersbur added a comment.

Some bikeshedding: Calls to `AvoidConcat` could be avoided by always inserting a space between tokens at the cost of making the output larger. In the current form, the flag could also be named `-fminimize-whitespace`.
