Clear destination buffer updated by the previous run
Clear the destination buffer updated by the previous run in bench-memcpy.c and test-memcpy.c to catch the error when the following implementations do not copy anything. [BZ #19907] * benchtests/bench-memcpy.c (do_one_test): Clear the destination buffer updated by the previous run. * string/test-memcpy.c (do_one_test): Likewise. * benchtests/bench-memmove.c (do_one_test): Add a comment. * string/test-memmove.c (do_one_test): Likewise.
