+ (e.g. next_nonnote_insn). Rather than create const shadow
+ functions, we can cast away const-ness in calling these interfaces

+ modify its argument and the return value is only used in a const
+ context. (This can be somewhat dangerous as these assumptions can
+ change after the fact). Beyond these uses, most other cases of
