This reverts commit 69dd89fdcbd846375a45e2fe3a88710887236d7a. This reverts commit 04000c2f928a7adc32138a664d167f01b642bef3. The current states breaks libstdc++ usage (https://reviews.llvm.org/D119136#3455423). The fixup has been reverted as it caused other valid code to be disallowed. I think we should start from the clean state by reverting all relevant commits.
