commit 3904fd85d3fdf0573e9a1e12e32bcd8cb246f549
Author: Wilco Dijkstra <wdijkstr@arm.com>

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.
