Just replacing AUTOUPDATE with NOAUTOUPDATE, and removing the autoupdate script. Tests will still run, but autoupdate may need to be fixed if significant changes are made. I noticed this while trying to autoupdate for #4007 (because we verify that tests have been autoupdated). Autoupdate was likely broken by #3449. Trying to run with no changes gives: ``` CHECK failure at testing/file_test/file_test_base.cpp:801: !absl::GetFlag(FLAGS_test_targets_file).empty(): Missing --test_targets_file. ``` This is because the `file_test` rule creates a file with test inputs that it runs with, which the prebuilt binary doesn't provide. A local kludge to create a `file_test` target not using prebuilt_binary showed another error: ``` : CommandLine Error: Option ': CommandLine Error: Option 'parser_debug' registered more than once! LLVM ERROR: inconsistency in registered CommandLine options trace_phase' registered more than once! LLVM ERROR: inconsistency in registered CommandLine options ``` I'm thinking here that the explorer code hasn't been in enough use, and we're seeing some rot as a consequence. Rather than trying to maintain it, I'm suggesting to go with NOAUTOUPDATE.
