The flag can be used when creating AOT snapshots. The resulting file can be used with package:vm/dwarf/convert.dart to convert DWARF-based stack traces to stack traces with function, file, and line number information. Currently the saved file will be an ELF file with DWARF debugging information, but this is subject to change in the future. To avoid being affected by any changes in format, read the DWARF information from the file using Dwarf.fromFile() in package:vm/dwarf/dwarf.dart. Also adds --dwarf-stack-traces to the VM global flag list, so its value at compilation will be read out of snapshots by the precompiled runtime. Fixes https://github.com/dart-lang/sdk/issues/39512, which was due to a missing compiler::target:: prefix for Instructions::HeaderSize() in BlobImageWriter::WriteText(). Exposes the information suggested in https://github.com/dart-lang/sdk/issues/39490 so that package:vm/dwarf can appropriately convert absolute PC addresses to the correct virtual address for a given DWARF line number program.
