[PATCH] D70235: [clangd] Add isHeaderFile helper.

[Sam McCall via Phabricator via cfe-commits]

sammccall added a comment.

As discussed offline, we still want to respect the langopts signal, but we also want to treat *.h as a header if it's not present. So the function needs to take filename and langopts.
