Thanks @smanna12. It looks like the revert happened in https://github.com/llvm/llvm-project/commit/c92ad411f2f94d8521cd18abcb37285f9a390ecb. Adding @topperc for awareness.

The change looks good to me and matches what was originally done in https://github.com/llvm/llvm-project/commit/7372c0d46d2185017c509eb30910b102b4f9cdaa.
