#286: Change detect_leaks=0 to detect_leaks=1 in asan-test target.
LSAN suppressions for CPython intentional leaks (interned strings, type
objects, small int cache, etc.) were already in sanitizers/asan.supp.
Now that #266 and #275 are fixed, real McRogueFace leaks will be caught.
#284: Add make massif-test target that runs stress_test_suite.py under
Valgrind Massif for heap profiling. Output goes to build-debug/massif.out,
viewable with ms_print.
Closes#286, closes#284
