Previously the MallocNanoZone envvar would be set to 0 on Darwin for the LLDB shell tests, but this should guarded behind ASan being enabled as opposed to simply running the test suite behind Darwin. This required that the LLVM_USE_SANITIZER option be added as an attribute to the lit config for shell tests.
