When builds on Darwin are configured with ASan, running tests will emit a
warning about malloc's nano zone that can interfere with the test output and
cause failures. Setting the environment variable `MallocNanoZone` to 0 will
remove this warning and allow the tests to run as normal.

Subject: [PATCH] [lldb][lit] Add MallocNanoZone envvar to Darwin ASan builds
When builds are Darwin are configured with ASan, running tests will emit
a warning that can interfere with the test output and cause failures.
Setting the environment variable `MallocNanoZone` to 0 will remove this
warning and allow the tests to run as normal.
