I've bootstrapped/regtested this patch on s390-ibm-linux and s390x-ibm-linux
without regressions.  It also fixes PR 24621.

I haven't checked for performance regresions, but I don't expect any
major issues here.

Is the intent of this patch that now the various special cases in
find_reloads and gen_reload that try to handle a PLUS as 'operand'
and reload it should never trigger any more?  If true, we should
remove them -- this would allow me remove one of the ugliest parts
of the s390 backend ...

Bye,
Ulrich
