Fix 203877 and 301229 increase to 16Mb maximum allowed alignment for memalign() and posix_memalign
Note that VG_(arena_memalign) is not used by core or tools for the moment.
We have one single maxima for both the V core/tools and the client.
Enhanced memcheck/tests/memalign2.c to test 4 Mb and 16 Mb alignments.
