Fixes #<!-- -->84658.

Assuming these were typos in the first place.

I am unsure of the best way to ensure that both sides of the preprocessor condition in `libc/include/llvm-libc-macros/stdbit-macros.h` are tested. Could someone point me in the right direction for adding test coverage to the non `__cplusplus` branch? Or maybe it is being tested and I've missed it.
