The problem is the define_split at sh.md line 893 (the part at 945). Or
actually, it's sh_find_set_of_reg. Adding this

Fixes the test case for me. It seems I should really fix PR 67061, which looks
like the same issue (and the other issue with sh_find_set_of_reg which was
fixed with a modified_between_p).
