Add support for tcmalloc
Beside improving performance of KLEE, tcmalloc allows to track used memory correctly. If available, tcmalloc is automatically used during compile time. This can be forced to be: - disabled using --without-tcmalloc - enabled using --with-tcmalloc In the second case, configure will fail if tcmalloc is not found or usable. Both versions of tcmalloc a minimal and normal version.
