be replaced if malloc() et al are replaced by a tool. This is because different tools implement the function in different ways. Add an appropriate malloc_usable_size() replacement to each of Memcheck, Helgrind, DRD, Ptrcheck, Massif. Update memcheck/tests/malloc_usable and add massif/tests/malloc_usable. Merged from the DARWIN branch. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@9193
