Artifact Builds in Automation, now with green tests

A quick update, because I've seen a few questions about this. Bug 1315032
<https://bugzilla.mozilla.org/show_bug.cgi?id=1315032> has landed, meaning
if you typically develop with "--enable-artifact-builds" locally,
"--artifact" will be added to your try syntax by "mach try". This can be
undone by either passing "--no-artifact" to "mach try" or removing
"--enable-artifact-builds" from your mozconfig.
Some jobs aren't compatible with artifact builds yet. Most of these have
pending fixes or will be investigated shortly, but this has some potential
to be confusing. In particular, some Tier-2 TaskCluster builds and the
"Sym" job are failing.
We've focused on greening up Tier-1 builds and tests so far -- these jobs
should have reliable results.
