[PATCH] D126907: Deferred Concept Instantiation Implementation Take 2

[Mark de Wever via Phabricator via cfe-commits]

Mordante added a comment.

This change breaks libc++'s modular build see build https://buildkite.com/llvm-project/libcxx-ci/builds/12991
Reverting this commit on top of yesterday's build (before your revert) fixes the issue.

libc++'s modular build uses Clang's pre-C++20 modules.

It can be reproduced building libc++ and running the following lit invocation
`${LIT} -Denable_modules=True libcxx/test/libcxx/ranges/range.adaptors/range.all/all.nodiscard.verify.cpp`

If you need assistance testing a new version of this patch on libc++ please let me know.
