I think this might have broken the CI tests. I am trying to replicate the test error on my local machine and in that case revert these last batch of changes to loongarch.

See here - https://github.com/llvm/llvm-project/actions/runs/10889855545/job/30217355303

if anyone is around now and can have a look I would appriciate it since I am slated to do this release now.
