Nathan Froyd 676dfa4114 Bug 1322396 - report external resources of documents when flushing use counters in tests; r=dholbert 
Our use counter tests force reporting of use counters from documents to
make the tests more deterministic: relying on the default
report-at-document-destruction behavior would introduce any number of
intermittents.  However, documents may have any number of external
resource documents, and we have no mechanism for forcing a deterministic
reporting of the use counters from those documents.  Relying on those
external resources to have been destroyed (and thereby reported their
use counters) when we examine the values of the use counters in question
is a recipe for intermittent failures.

Therefore, we introduce an optional report kind for use counter
reporting: if a document is reporting its use counters for the purposes
of a test, we will also report the use counters for the document's
external resource documents.  This change makes everything more
deterministic.
