It's generally a mistake to consider testcases redundant unless actually
identical. While two testcases may appear to test the same thing with the
current implementation while the compiler is working correctly, a
reimplementation of a feature or diagnostic could cause them to take
different code paths, and a regression could break one similar case but
not the other.
