[PATCH] D119136: [clang] Implement Change scope of lambda trailing-return-type

[Corentin Jabot via Phabricator via cfe-commits]

cor3ntin updated this revision to Diff 422282.
cor3ntin added a comment.

After offline discussion with Aaron, we decided that "can not appear here" was a
sufficient diagnostic, so I have implemented that.
A better solution would be to track which captures fail, and collect the diagnostics
to emit them after the parameter list, but this seem to add a lot of complexity
for something few people are likely to encounter.

- Add tests
- A diagnostic for use before capture  could be emited twice when parsing

a template parameter list, this was fixed.
