Optimize roles_is_member_of() with a Bloom filter.
When the list of roles gathered by roles_is_member_of() grows very
large, a Bloom filter is created to help avoid some linear searches
through the list. The threshold for creating the Bloom filter is
set arbitrarily high and may require future adjustment.
