So, question is: is gcse wrong to reuse a value from inside a libcall
block, or shouldn't the backend have created one in the first place?

Both.

        * config/sh/sh.md (udivsi3): Don't put udivsi3_i4_media instructions
        into a libcall block.
        (divsi3): Likewise divsi3_i4_media.

OK.
