If the $wp_user_roles global is defined, it is used instead of the
roles in the options table.  Your plugin can store modifications in
site options and then use that site option to populate $wp_user_roles
during init.  On wordpress.com we just hard code the $wp_user_roles
array on wp-config since we rarely ever change it.  This avoids going
to the options table or site options table for role information.
