* 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.
