instrumentation of the of 'base' and 'base + len' in a "if (len !=

instrument 'base + len' inside a sequence, and then insert that
sequence right before the current insertion point. Then, to
instrument 'base + len', just get an iterator on that statement.
And do not forget to update the pointer to iterator the function
received as argument.

From-SVN: r196102
The mmap() call which reserves the arena should have MAP_NORESERVE
flag as in typical cases this memory will never be (fully) needed.
This matters in environments which do not do Linux style memory
overcommit, such as OpenIndiana/OpenSolaris/Solaris.
The MAP_NORESERVE flag does not exist on all operating systems
(for example FreeBSD). Therefore we define it to zero value in
case it does not exist.
Fixes issue 21.
