Add page tests to string/test-strnlen.
May be tricky for otimized implementations to handle strings around page boundary once, for instance, it is performed unaligned loads or when maxlen is used as a hint for vectorized loops. The test cases should unveil regression bugs on these cases. To some extend do_random_tests in string/test-strnlen tests strings placed at page end but it does not cover all cases. So this change adds tests which consists of placing strings of varying sizes ending at the page boundary. It also combines with different values of maxlen. Tested on ppc64le and x86_64. * string/test-strnlen.c (do_page_tests): New function to check length of strings ending at the page boundary. (test_main): Added call to the do_page_tests function.
