We now use it during testing to close the loop on the question of whether the file is "complete" in the sense that it satisfies the minimal "no-op" implementation of the abi. We also moved from having a hand-curated include file to using the actual interface file which should be the root truth for what needs to be in there. We discovered a few additional functions that were in asan_interface.h but aren't strictly part of the interface between the instrumentation and the runtime but rather are used intra-runtime. Some other routines living in asan_interface.h are really documented "helper" functions. Maybe these should be aggregated somewhere else and/or under a different namespace. For now we ignore those entrypoints by listing them in compiler-rt/lib/asan_abi/darwin_exclude_symbols.inc
