- Remove dead Isolate::IsTopLevelParsing. - Remove dead TraceFunctionEntry/Exit. - Migrate more tracing flags to flag_list.h to allow code elimination in non-debug modes. - Require an explicit Zone parameter for CheckedHandles. - Remove side-effects from RuntimeEntry constructor. out/ProductX64/exe.stripped/dart_precompiled_runtime 4063464 -> 4046952 (-16k) Change-Id: Iffd3de25a03d2354cdecf2d79aa761c33ab08bd3 Reviewed-on: https://dart-review.googlesource.com/c/83120 Reviewed-by: Ben Konyi <bkonyi@google.com> Commit-Queue: Ryan Macnak <rmacnak@google.com>
