The goal of this PR is to add support for backing files to shadow address ranges of machines, so we can run machines directly mapped from disk:

  • shadow uarch state
  • shadow processor
  • shadow tlb

It also adds a "penumbra" region that only exists during runtime to the end of the machine state, however it's not stored in disk, in order to keep the interpreter efficient.
