This should be IRT_DEV_FILENAME.  IRT_FILENAME is not supported in the browser,
and we only have it queryable in existing ABIs for compatibility.  New ABIs
should not return it -- PNaCl doesn't.

So, if you want to add this, it should be behind a flag (as we discussed in
e-mail before).  But putting this behind a flag adds enough complexity that I
would want to have a test for that.  So can we put this change on hold until
PPAPI works under Bare Metal Mode and we have enabled tests for it on the bots?

I see. I misunderstood. Let's keep this suspended for a while.
