* tree-vect-generic.c (get_compute_type, count_type_subparts): New
functions.
(expand_vector_operations_1): Use them. If {L,R}ROTATE_EXPR
would be lowered to scalar shifts, check if corresponding
shifts and vector BIT_IOR_EXPR are supported and don't lower
or lower just to narrower vector type in that case.
* expmed.c (expand_shift_1): Fix up handling of vector
shifts and rotates.
