We're seeing some crashes in there on Windows 10 insider, but hard to do anything without symbols (I think?)

Microsoft updated their symbol server a few months ago: https://blogs.msdn.microsoft.com/windbg/2017/10/18/update-on-microsofts-symbol-server/

Unstated in that blog post is that it no longer serves hits for .pd_ files, only .pdb files. It apparently does support on-the-fly compression but I don't know exactly how. Unfortunately my script that fetches missing symbols from Microsoft's symbol server was only trying to fetch .pd_ files, so it hasn't actually been working for a while now. :-/

I changed the script to fetch .pdb files:
https://hg.mozilla.org/users/tmielczarek_mozilla.com/fetch-win32-symbols/rev/b3ad2f800830

and kicked off a new run of the scheduled task:
https://tools.taskcluster.net/groups/XlZwgDAOQ_yhfw1h2Bw4uw/tasks/X8wJ0XiOQje8j9gDrAfZLw/details

and it uploaded 427 symbols(!) so we should be clear of whatever backlog we had. If you have specific crash reports of interest we can easily reprocess them, or I can spot-check that we have the symbols in question.

I reprocessed the crash in bug 1419052 comment 0 and it has symbols now, so this seems fixed.
