handle all dispatching for colon operator in do_colon_op function
* ov.cc (do_colon_op): Handle all dispatching here, but using lookup
based on argument vector passed to feval instead of determining
dispatch type separately.
* pt-colon.cc (tree_colon_expression::evaluate): Simply evaluate
arguments and pass them to do_colon_op.
* test/colon-op: New test directory.
* test/module.mk: Update.
