add --with-address-sanitizer option to Jamroot build file

AddressSanitizer (built into gcc since 4.8) helps tracking down memory errors. Similar to valgrind --tool=memcheck, but with MUCH less overhead (slowdown of 2x reported by [1]).

Unfortunately, if you switch it on explicitly, a test case fails (mert/DataTest.cpp:56) reporting a memory leak, even though there is a scoped_ptr supposed to take care of that. Otherwise harmless.
