Per code coverage reports, we had zero regression test coverage of these functions. That came back to bite us, as apparently that's allowed us to miss discovering misbehavior of this code with AIX's xlc compiler. Install relevant portions of the test cases added in 97957fdba, 2f0472030, 19fa97731. (Assuming the expected outcome that the xlc problem does appear in back branches, a code fix will follow.)
