The folder is now set in `add_llvm_unittest`. it is not necessary anymore to assign it in the CMakeLists.txt. This means that it will not be put into a "DebugInfoTests" folder because `add_llvm_unittest` doesn't know about it. However, these subfolders were hard to keep consistent (only users of cmake IDE project generators would even see them and likely ignore them when they make a change). I only kept them when there was another mechanism such as `add_llvm_debuginfo_unittest` function that would enforce it.
