Perhaps this could be fixed by putting a stmt_addend value into the
strinfo structs.
Bootstrapped on x86_64 and s390x. No regressions.
Ok for mainline?

Can you please explain this stmt_set_p stuff? dont_invalidate should be
only set on strinfos that will be seen by the immediately following
maybe_invalidate call (at the end of handle_builtin_strcpy caller -
strlen_optimize_stmt). If you set it on which unshare_strinfo is called,
if there

Why the force_operand? You've got register inputs. Either the target
is going to support the operation or it isn't.
Seems to me you can check the availability of the operation in the
optab and pass that gen_rtx_fmt_ee result to rtx_cost
it without seeing a clear reason for
it. So I've removed it now.
Saving cost data dependent on speed, which is non-constant.
You probably need to make this a two dimensional array.
Fixed.
Here is an updated version.
