[PATCH] D133052: [clang] Avoid crash when expanding conversion templates in concepts.

[Luke Nihlen via Phabricator via cfe-commits]

luken-google added a comment.

Because of the change to `InsertNode` to not assert on already cached concepts this patch now works. If I try to catch the recursive expansion on a higher level the test in `concepts.cpp` for 2-level concept expansion fails. There are some finite recursive use cases for template expansion.
