Gnuwin32 is required, for now, when you run tests (check, check-all,
clang-test).
Then, you would not need to update your %PATH% to specify
LLVM_LIT_TOOLS_DIR to CMake.

Let me know if you know other (llvm|clang)-tests-compatible tools
other than gnuwin32 (and msys).

FYI, some clang/llvm tests are marked as "REQUIRES: shell". They rely
on sh behavior and they are skipped if bash.exe is not found in your
%PATH%.
