re PR middle-end/81698 (expand_case uses wrong edge as default edge)

	PR middle-end/81698
	* stmt.c (emit_case_dispatch_table): Add DEFAULT_EDGE argument,
	instead of computing it in the function.  Formatting fix.
	(expand_case): Don't rely on default_edge being the first edge,
	clear it if removing it, pass default_edge to
	emit_case_dispatch_table.
	(expand_sjlj_dispatch_table): Pass NULL as DEFAULT_EDGE, formatting
	fix.
