/// ObjectFileMinidump is created only to be able to save minidump core files
/// from existing processes with the ObjectFileMinidump::SaveCore function.
/// Minidump files are not ObjectFile objects, but they are core files and
/// currently LLDB's ObjectFile plug-ins handle emitting core files. If the
/// core file saving ever moves into a new plug-in type within LLDB, this code
/// should move as well, but for now this is the best place architecturally.
