LOG: llvm/Support/Debug.h: Suppress warnings with -Asserts. [-Wunused-variable]

Re. setCurrentDebugTypes(X,N), the only user is llvm-ml.cpp (exc. DebugTests)
since llvmorg-15-init-8355-g82ecf9a0b1b3.

FIXME: X and N are evaluated regardless of NDEBUG.
Could we avoid evaluating (but w/o warnings) with NDEBUG?
