--- Comment #8 from Richard Henderson <rth at gcc dot gnu.org> ---
Indeed, if I force used_in_cond_stmt_p to return false, which forces
the use of the emit_cstore path, which means we return a proper
boolean value instead of a CCmode value, the test case doesn't ICE.

Moreover, combine does in fact remove the redundant compare and we
are left with

        cmp     w0, 39
        ccmp    w0, 10, 4, ne
        bne     .L19

I think I was wrong to approve the ccmp patch with the used_in_cond_stmt_p
logic in the first place, and that it should all be removed.
