perf bench: Allow passing an iteration count to "bench mem mem{cpy,set}"
"perf stat ... perf bench mem mem..." is pretty meaningless when using small block sizes (as the overhead of the invocation of each test run basically hides the actual test result in the noise). Repeating the actually interesting function's invocation a number of times allows the results to become meaningful.
