Regalloc2 uses randomized allocation order, right? Is there still value in doing this?

It's randomized but in two tiers, "preferred" and "non-preferred" (which we use for caller-saves and callee-saves respectively, i.e. prefer a shorter prologue). Those are still constant for the machine backend though (here); this issue is about slightly tweaking the division between those two classes. It would need a bit of plumbing to make this ABI-dependent, I think.
