I noticed this inconsistency while reviewing D107509 <https://reviews.llvm.org/D107509>.

For the MSVC environment, Clang currently annotates `getc_unlocked` with `nocapture`, which could technically be wrong if `getc_unlocked` were an unrelated function. MSVC's CRT doesn't define `*_unlocked` functions. https://godbolt.org/z/GreGM6x8G.

(MSVC does define `*_nolock` functions, which look similar, but I haven't looked closely.)
