Upcoming patches are revamping expression evaluation significantly. It therefore seems prudent to try to ensure that the coverage of the existing evaluation code is high. This commit adds coverage for the cases that can reasonably be tested. There's still a bunch of unreachable error messages and such, but otherwise this achieves nearly full regression test coverage (with the exception of the unused GetAttributeByNum/GetAttributeByName).
