That also occurred to me, but IMO it's not crystal clear; for example, ivdep

Hi,
this adds support for 2 optimization hints pertaining to loops in Ada, namely
Loop_Optimize (No_Vector) and Loop_Optimize (Vector), by reusing the Ivdep
approach in the middle-end (ANNOTATE_EXPR node) and directly setting the
dont_vectorize and force_vectorize bits of the 'loop' structure.
