I'm supportive of merging this but only once we've decorated the test accordingly (CC @Michael137). Currently this causes a test failure on Apple Silicon: https://ci.swift.org/view/all/job/llvm.org/view/LLDB/job/as-lldb-cmake/

Will / should this still be fixed for 19?

If you cherry-pick 2bcab9ba7139cfa96c85433fa85b29c8a6d7008b alongside it, then we should be fine.

This is a revert of b1fcc18.

These tests weren't working on Ubuntu 22.04 or Fedora 37-40. I'm not
sure exactly why, but it seems like they may be incompatible with
libstdc++. Also, despite the fact that the tests were using the system
libstdc++, the tests were only run when libcxx was enabled.

I tested this with a RelWithDebInfo build and the tests passed.

Fixes llvm#106475
