Jeff Muizelaar c7fe1a2838 Bug 1619978. Crash sometimes if we fail to get the SystemFontCollection. r=jfkthame
WebRender won't support GDI fonts so we need to figure out what to do
with the users that are currently using them. This should help give us
better diagnostics on what's going wrong.

gfxCriticalError only crashes on Nightly and Beta builds
