[lld] r242885 - [ELF] Protect write access to the ELFLinkingContext::_cidentSections by a mutex

[Simon Atanasyan]

Hi,

The r242885 is a fix for the PR24205. I forgot to mention it in the
commit message. It would be good to backport the fix to the 3.7. The
commit can be merged into the release_37 without any conflicts.

Regards,
Simon
