AFAIK this was reverted in the release branch already, in 67d0736b14c7888e63af16dcc71129ce07383010 <https://reviews.llvm.org/rG67d0736b14c7888e63af16dcc71129ce07383010>, so the branch should be good wrt that. @chrisjackson expressed a desire to backport the working version of the commit though.

The current reapplied version of this in the main branch with the fix from rG2537120c8 <https://reviews.llvm.org/rG2537120c870c04893636f171f553024f378c2de8> seems to work fine for me now.
