Failed test `ORC-x86_64-darwin :: TestCases/Darwin/x86_64/trivial-cxa-atexit.S` on macOS with 13.0.1-rc2

Hi,

While release testing I ran into this issue:

FAIL: ORC-x86_64-darwin :: TestCases/Darwin/x86-64/trivial-cxa-atexit.S (78090 of 91780)

Is this a blocker for 13.0.1?

@tru I was not able to reproduce this issue in the llvmorg-13.0.1-rc2 tag or in main. Could you share your cmake config?

Is this a blocker for 13.0.1?

There are no changes to orc or the orc runtime between 13.0 and 13.0.1-rc2, so I suspect this is not a regression but a config change or something.

Incidentally, the version of the ORC runtime in 13.0.* has some debug fprintf(stderr that was later fixed on main 😭

I went back and looked and this is not a regression in the latest version. It's happening all the way back in 13.0.0-rc4 - it's the oldest version of logs I have around.

My CMakeCache.txt is here: https://gist.github.com/47022e217b08861fcaa1c8a8eaecb012

Reproduced in a release build of 13.0.1-rc2. llvm_jitlink_setTestResultOverride is getting dead-stripped. This issue only impacts our tests. Fix: https://reviews.llvm.org/D117609
