what populates the workaround list? the way this works in chrome is the browser
proc generates a bunch of stuff into the command line for the gpu process when
then gets populated here. maybe the command line parameter isn't actually used?

Some workarounds are set automatically based on the gpu, a good example being
the adreno 420 fix for framebuffer deletion.

The commandline provides additional workarounds (see
GpuDriverBugList::AppendWorkaroundsFromCommandLine).  In this case, the
commandline happens to be empty.  I'm not sure we want to actually use a command
line for this, maybe it would be better to just construct an empty command line
and pass that in.
