The patch in http://reviews.llvm.org/D106431 landed in commit 4a097efe7784767b7d12ffcb8f2b22b9f4d045e2 to the main branch.
However, this patch was also backported to upcoming release 13.0.0 in
commit 8dcdfc0de84f60b5b4af97ac5b357881af55bc6e, which makes this entry
in the release notes **NOT** a new thing for the purposes of 14.0.0.
