gen_exp currently supports the 's' (string) operand type. It would

that too. However, the rtx codes that have string operands should
be very rarely used in hard-coded define_insn/expand/split/peephole2
rtx templates (as opposed to things like attribute expressions,
where const_string is commonplace). And AFAICT, no current target
does use them like that.
This patch therefore reports an error for these rtx codes,
rather than adding code that would be unused and untested.

OK. And we'll get a pretty good sense if a port is doing something
really weird in this space from my tester once this patch goes in.
