Hmmm, the rs6000/ entries have an explicit dir name:

rs6000/powerpc-cell32l-expedite = r1,pc,r0,orig_r3,r4
rs6000/powerpc-cell64l-expedite = r1,pc,r0,orig_r3,r4

Maybe all we need is to prefix the x86 ones with i386/ ?

i386/amd64-expedite = rbp,rsp,rip
i386/i386-expedite = ebp,esp,eip
i386/x32-expedite = rbp,rsp,rip

I don't know if that works.  I see that that prefix was actually
there recently, and it was removed by 414c838a722e recently.
