poly_int: vec_perm_indices element type
This patch changes the vec_perm_indices element type from HOST_WIDE_INT
to poly_int64, so that it can represent indices into a variable-length
vector.

* vec-perm-indices.c (vec_perm_indices::series_p): Likewise.
(vec_perm_indices::all_in_range_p): Likewise.
(tree_to_vec_perm_builder): Check for poly_int64 trees rather
than shwi trees.
* vector-builder.h (vector_builder::stepped_sequence_p): Handle
polynomial vec_perm_indices element types.
