S390: Do not clobber r7 in clone [BZ #31402]release/2.39/master
Starting with commit e57d8fc97b90127de4ed3e3a9cdf663667580935
"S390: Always use svc 0"
clone clobbers the call-saved register r7 in error case:
function or stack is NULL.
This patch restores the saved registers also in the error case.
Furthermore the existing test misc/tst-clone is extended to check
all error cases and that clone does not clobber registers in this
error case.
(cherry picked from commit 02782fd12849b6673cb5c2728cb750e8ec295aa3)
