Add malloc micro benchmark
Add a malloc micro benchmark to enable accurate testing of the various paths in malloc and free. The benchmark does a varying number of allocations of a given block size, then frees them again. It tests 3 different scenarios: single-threaded using main arena, multi-threaded using thread-arena, main arena with SINGLE_THREAD_P false. * benchtests/Makefile: Add malloc-simple benchmark. * benchtests/bench-malloc-simple.c: New benchmark.
