Add more tests for memchr
This patch adds tests for len == 0 and tests for positions close to the beginning, which are equivalent to positions close to the end for memchr. * string/test-memrchr.c (test_main): Add tests for len == 0 and tests for positions close to the beginning, which are equivalent to positions close to the end for memchr.
