[Bug rtl-optimization/26479] suboptimal register allocation for return register

With -O2:
L4:
        addi r1,r1,128
        mr r3,r2
        ld r0,16(r1)
        ld r31,-8(r1)
        mtlr r0
        blr

With -O2 -fno-if-conversion:
L4:
        addi r1,r1,128
        ld r0,16(r1)
        ld r31,-8(r1)
        mtlr r0
        blr

I have not looked enough into the RTL to figure out why this is going wrong.
