Hi Hans,
Could you please cherry pick rG41206b61e30c into the release-10 branch. This
cleanly cherry-picks and passes check-llvm on amd64 Ubuntu 18. The patch fixes
a performance regression where in certain circumstances, debugging information
could grow quadratically with the size of a basic block. This behaviour was
introduced in llvm 9, it'd be great to fix it for llvm 10.
