OpenMPI Users - Is Anyone Using openmpi-clang33 or openmpi-clang34?

[Chris Jones]

Hi,

Another clean up suggestion is to remove all clangs apart from 11+ for macOS11(arm). I just noticed the buildbots building the clang-9.0 version for arm, but its worth noting that clang 9.0 and 10 are not reliable for arm, I have seen them generate bad code, fail with ICEs, so really there is little point in providing all but the clang11(and newer) version which is the first version with reliable arm support.
