Add test for folding of == and != for arrays. We don't directly support this today at all. In practice, though, simple constant arrays are detected as equal in the constant-folding pass because they hit the `x == x` self-equality check (using `IsSameExpressionTree`). This does not work for our inequality tests, though, so those do not fold.

Add support for constant-folded array inequality checks. This isn't something I expect to occur often. However, we have always reported that array-ctors with constant arguments are compile-time constants, and `compareConstant` is supposed to be implemented for all compile-time constants.
