cmd/internal/obj/{arm,s390x}: make return jump print nicer
When a function with non-zero frame size makes a return jump
(RET target), it assembles to, conceptually,
MOV (SP), LR
ADD $framesize, SP
JMP target
We did not clear some fields in the first instruction's Prog.To,
causing it printed like (on ARM)
MOVW.P 4(R13), (R14)(R14)(REG)
Clear the fields to make it print nicer.
