I'd be surprised if we could do as well if we lower this to ifs.
I think we probably want to keep a multi-way branch until rtl.

But something more like

	multi-goto [ 1: label1, 2: label2, 3: label3, else: label4 ];

than a switch statement per-se.  You could still use SWITCH_EXPR,
probably, so long as all the labels and values are collected in
the node.
