! First loop (A=LOG(X)) is vectorized using peeling to align the store.

! Same for the second loop (B=LOG(Y)).

! Third loop (C = A + B) is vectorized using versioning (for targets that don't

! support unaligned loads) or using peeling to align the store (on targets that

! support unaligned loads).
