A year ago I submitted a change to replace AnyError with tests for specific errors (see https://github.com/elves/elvish/commit/87656c99). This does something similar for DoesNotCompile. This ensures the test does what is implied and makes correlating specific unit tests with compilation errors easier. This includes a couple of changes to compilation error messages to improve readability (IMHO) but those are not the primary purpose of this change. Related #1560
