* tree-vectorizer.h (enum stmt_vec_info_type): Add new value for
shift.
(vect_get_slp_defs): Add arguments.
* tree-vect-loop.c (vect_create_epilog_for_reduction): Pass scalar
operands to vect_get_slp_defs.
(vectorizable_reduction): Fix comment, pass scalar operands to
vect_get_slp_defs.
* tree-vect-stmts.c (vect_get_vec_def_for_operand): Use operand's
type to determine number of units in the created vector.
(vect_get_vec_defs): Pass scalar operands to vect_get_slp_defs.
(vectorizable_conversion): Fix comment.
(vectorizable_shift): New function.
(vectorizable_operation): Move code that handles shifts to
vectorizable_shift.
(vectorizable_type_demotion): Fix comment, pass scalar operands to
vect_get_slp_defs.
(vectorizable_type_promotion, vectorizable_store): Likewise.
(vectorizable_condition): Fix comment.
(vect_analyze_stmt): Call vectorizable_shift.
(vect_transform_stmt): Likewise.
* tree-vect-slp.c (vect_get_constant_vectors): Add new argument.
Use it as the operand to create vectors for, except reduction
initial definition and store. Use operands type.
(vect_get_slp_defs): Add new arguments. Pass them to
vect_get_constant_vectors.
