[PATCH] D41976: Low-hanging fruit optimization in string::__move_assign().

[Timothy VanSlyke via Phabricator via cfe-commits]

tvanslyke added a comment.

Since `__clear_and_shrink()` is private the test covers copy and move assignment.  I also ran the libcxx/strings/basic.string and std/strings tests with a hard-coded `assert(__invariants());` at the end of `__clear_and_shrink()` and saw no failures.

I don't have commit access myself so I've added the test to the diff.
