Castable: Optimize Switch()

Use a bloom-filter-style early rejection to eliminate whole blocks of
case statements from the switch type checks. Much like IsAnyOf(), the
list of types considered are recursively tested as a whole and
then binary-chopped if there's a potential match, until we test the
individual switch case types.
