Stefan Liebler bfdb731438 S390: Fix handling of needles crossing a page in strstr z15 ifunc-variant. [BZ #25226]
If the specified needle crosses a page-boundary, the s390-z15 ifunc variant of
strstr truncates the needle which results in invalid results.

This is fixed by loading the needle beyond the page boundary to v18 instead of v16.
The bug is sometimes observable in test-strstr.c in check1 and check2 as the
haystack and needle is stored on stack. Thus the needle can be on a page boundary.

check2 is now extended to test haystack / needles located on stack, at end of page
and on two pages.

This bug was introduced with commit 6f47401bd5
("S390: Add arch13 strstr ifunc variant.") and is already released in glibc 2.30.
