stmt.c: Don't include insn-codes.h.

	* stmt.c: Don't include insn-codes.h.
	(expand_end_case): Machine specific logic moved to expr.c.
	No need to worry about __builtin_classify_type.
	(check_for_full_enumeration_handling, emit_case_nodes):
	Kill #if 0 blocks.

	* builtins.o (expand_builtin_classify_type): Split up so code
	can be shared with fold_builtin_classify_type.
	(type_to_class, fold_builtin_classify_type): New functions.
	(fold_builtins): Handle __builtin_classify_type.

	* expr.c (do_tablejump): Now static.
	(case_values_threshold, try_casesi, try_tablejump): New;
	code mostly from stmt.c (expand_end_case).
	(expr.h): Update prototypes.

	* Makefile.in (stmt.o): Update dependencies.
