[PATCH 9/14] Enforce whole-vector-shifts to always be by a whole number of elements

The VEC_RSHIFT_EXPR is only ever used by the vectorizer in tree-vect-loop.c (vect_create_epilog_for_reduction), to shift the vector by a whole number of elements. The tree code allows more general shifts but only for integral types. This only causes pain and difficulty for backends
