[PATCH] D34256: [PR33394] Avoid lexing editor placeholders when running the preprocessor only

[Ben Langmuir via Phabricator via cfe-commits]

I agree with not detecting these during PP-only, but there's nothing wrong with `<#>`.  It's either not a placeholder, or it's part of a placeholder like `<#>#>`, which is a placeholder containing the text ">".  Similarly, `<##` could be the start of an empty placeholder `<##>`.
