Description

This is a meta tracking issues for LLVM workarounds that should eventually be removed once newer LLVM versions render the workarounds obsolete. Please edit this issue to backlink to relevant PRs or issues as suitable (preferably open new issues for specific LLVM workarounds). You can also leave a FIXME(#135981) or a FIXME backlinking to a dedicated issue in code to backlink to this tracking issue. Please remove entries if they are cleaned up.
