Replace forms of `assertTrue(err.Success())` with `assertSuccess(err)` (added in D82759). * `assertSuccess` prints out the error's message * `assertSuccess` expresses explicit higher level semantics, both to the reader and for test failure output * `assertSuccess` seems not to be well known, using it where possible will help spread knowledge * `assertSuccess` statements are more succinct Differential Revision: https://reviews.llvm.org/D119616
