This will remove the --error_format from dartc - in here analyzer means any
analyzer. if you want to do something specific to the new analyzer use
configuration['compiler'] == 'new_analyzer'

I actually added support for --machine to both dartc and the new analyzer, so I
figure I'll just pass the same flag in for both.
