[release-branch.go1.9] bytes, strings: fix comparison of long byte slices on s390xrelease-branch.go1.9
The existing implementation of bytes.Compare on s390x doesn't work properly for slices longer
than 256 elements. This change fixes that. Added tests for long strings and slices of bytes.
Fixes #26118
