CorpseSymbolTest was previously looking up the symbol for `malloc`. ASAN builds overrides `malloc` with its own implementation, which causes the test to fail. We now change CorpseSymbolTest to look up `tolower` from the standard C library instead. A test in CorpseSnapshotTest was doing 100 interactions of creating Snapshots and requesting their threads list. This was done to see if the operations leaked any mach ports. As a result, this test was taking on the order of 1.1 seconds to run for a Release / Debug build, and ~9 seconds for an ASAN build. CorpseSnapshotTest is now fixed to run that test exactly once and confirm that there's no increase in mach ports allocated. CorpseSnapshotTest now takes 60-90 ms to run.
