[PATCH] benchtests: Add more tests for memrchr

- Reply-to: "H.J. Lu" <hjl dot tools at gmail dot com>
bench-memchr.c is shared with bench-memrchr.c. This patch adds some
tests for positions close to the beginning for memrchr, which are
equivalent to positions close to the end for memchr.
Any comments?
H.J.

* benchtests/bench-memchr.c (do_test): Print out both length
and position.
(test_main): Also test the position close to the beginning for
memrchr.
