As it appears this PR is stacked on top of #170517, which was reverted for a few issues, one of which [I reported](https://github.com/llvm/llvm-project/pull/170517#issuecomment-3634886648), I am not going to test it in its current state. @ilovepi If you want any testing against the kernel once this change has been updated, please feel free to ping me and I will be more than happy to do it.

This is now based on a new version of the base patch that only gets enabled when not using exceptions. The patch up the stack from this one removes that constraint. https://github.com/llvm/llvm-project/pull/175817 is perhaps the better stack to try, since it has all the fixes.
