Setting to P4, please restore to P3 if a C or C++ test showing this problem is
found.

It replaces rl->in with an reg_rtx different from rl->reg_rtx and confused
IRA. I don't know if it is a reload or IRA bug. This patch fixes the testcase.

I think, H.J., that is one more latent bug (i already saw several of them) in
reload inheritance optimization triggered by IRA which allocates dx for p69 and
p87 in subsequent insns
47:p65<-p69
151:p87<-mem[...].
I am not sure that your patch is right but you can commit it for a review to
get some comments.
