Thanks. Still, I don't think there's anything wildly wrong with the quoted rtx
so I'm going to do s/PREV_INSN/prev_nonnote_nondebug_insn/g and assert that the
right insns and code_label is seen in cris_asm_output_case_end anyway. The
current PREV_INSNs are a little too presumptious (QED); there are no documented
promises broken at the SEGV.
