Provide a new dispatch mechanism for range-ops.

Simplify range_op_handler to have a single range_operator pointer and
provide a more flexible dispatch mechanism for calls via generic vrange
classes.   This is more extensible for adding new classes of range support.
Any unsupported dispatch patterns will simply return FALSE now rather
than generating compile time exceptions, aleviating the need to
constantly check for supoprted types.
