poly_int: prune_runtime_alias_test_list

This patch makes prune_runtime_alias_test_list take the iteration
factor as a poly_int and tracks polynomial offsets internally
as well.

gcc/
	* tree-data-ref.h (prune_runtime_alias_test_list): Take the
	factor as a poly_uint64 rather than an unsigned HOST_WIDE_INT.
	* tree-data-ref.c (prune_runtime_alias_test_list): Likewise.
	Track polynomial offsets.
