In the above I've tried to mirror what ix86_expand_prologue does
(also 3 ifs, no else/else if), but if you want, I can surely
swap stack_realign_fp and frame_pointer_needed case and add else
before if (stack_realign_fp).

I think I would prefer the else if. Same change in prologue, I guess.

Will change to most negative. Ok with that change?

Yes, thanks.
