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.

gcc/
	* vec-perm-indices.h (vec_perm_builder): Change element type
	from HOST_WIDE_INT to poly_int64.
	(vec_perm_indices::element_type): Update accordingly.
	(vec_perm_indices::clamp): Handle polynomial element_types.
	* 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.
	* int-vector-builder.h (int_vector_builder::equal_p): Likewise.
	* fold-const.c (fold_vec_perm): Likewise.
	* optabs.c (shift_amt_for_vec_perm_mask): Likewise.
	* tree-vect-generic.c (lower_vec_perm): Likewise.
	* tree-vect-slp.c (vect_transform_slp_perm_load): Likewise.
	* config/aarch64/aarch64.c (aarch64_evpc_tbl): Cast d->perm
	element type to HOST_WIDE_INT.
