This CL adds a flag, `assume-initialize-from-dill-up-to-date`, to the
`frontend_server` which will skip the check and potential invalidation
of files from the dill we're initializing from.
Normally the sources included in the dill is used to figure out what
files that was used to produce the dill has changed and thus needs to
be invalidated after we've initialized from it. If we didn't do that
we'd be in a bad state where some changes would not be discovered.
In some circumstances, though, we might know that the sources haven't
changed and the check is thus not needed. This could for instance be
if we're initializing from a dill that was just build by another build
system.
