bsalomon@google.com 604a56ad42 Run non-rendering benches in their own config. 
Currently benches that set fIsRendering = false are run as part of the first config run. This is problematic for several reasons.

1) Which config they are run as depends on the --config options passed to bench. If I run bench --config GPU --config 8888 then they will be run in the GPU config and not the 8888 config.

2) Their presence makes bench take longer to run when testing rendering changes or comparing one rendering config to another (e.g. GPU v 8888). This is especially true on Android.

3) When comparing runs of a single config across multiple bench runs (typically  with code changes) it isn't obvious from the output which benchs to ignore because they say are listed under as being part of the config.

This CL adds NONRENDERING as a config (open to name suggestions). Non-rendering tests are run in and only in the NONRENDERING config.

Will this screw up our bench bots/scripts/graphs? If so I think we should change them since running non-rendering tests separately makes a lot more sense than the current madness.
