--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Loop fusion is not implemented also strcpy is expanded inline too late (during
RTL expansion) and thus the two loops are exposed too late for the place where
it would be implemented.

Same reason for not vectorizing __builtin_tolower - it's expanded too late.
