Allow creating an analysis file without summaries (#136)
Allow creating an analysis file without summaries (#136)

We support passing in two separate booleans and it doesn't make sense to
ignore an explicit argument due to some other argument. It should be the
responsibility of some other code doing analysis to decide whether the
analysis requires summaries - the dart_ctx should only collect the data.
