[PATCH] D54377: Correctly instantiate `iterator_adaptor_base` when defining `pointer_iterator`

[Dylan MacKenzie via Phabricator via llvm-commits]

ecstatic-morse added a comment.

I added tests via `static_assert` and updated the description to mention the bug report.

Sorry, I wasn't sure if I was going to go to the trouble of setting up phabricator when I filed the bug.
