introduce Switch node
This is the new way of handling switch-jumps. The node contains a table which maps (ranges of) input values to proj numbers. Compared to a Cond-node this results in a clean consecutive sequence of Proj numbers (no searching for a free number for the default_pn anymore) and allows factoring multiple cases jumping to the same block in a single Proj (though we still need the optimisation in cfopt for that).
