LLVM had a bug where constructors with the same priority would not be stably sorted. This has been fixed upstream by
llvm/llvm-project#95532, but to avoid relying on a backport this commit works around the issue: The idea is that we lower the default priority of concerned constructors to make them sort correctly.
(cherry picked from commit 7db43f7, backport of #16420)
