This patch reduces the memory needed for a VtsTE by 25% (one word)
on 32 bits platforms. No memory reduction on 64 bits platforms,
due to alignment.
The patch also shows the vts stats when showing the helgrind stats.

The perf/memrw.c perf test gets also some new additional features
allowing e.g. to control the size of the read or written blocks.
