[libcxx-commits] [libcxx] Attempt to resolve GCC 13 bot slowness (PR #84344)

[via libcxx-commits]

https://github.com/EricWF created https://github.com/llvm/llvm-project/pull/84344

The bots are running slow because of the amount of IO done by
each worker every time they compile a file due to a number of
deprecated declarations.
