jochen@chromium.org d426cd1012 Use abstract configurations to switch between opt debug settings
The problem is that conditions are evaluated before configuration inheritance is resolved, so we can't just define a configuration like this:

'Optdebug': {
  'inherits_from': ['Debug'],
  'variables': {
    'v8_optimized_debug': 2,
  }
}

Instead, we have to put the different settings depending on the optimization level into separate configurations, and use conditions inside the concrete configurations to inherit from the correct base class.

Common settings go in the base configuration DebugBaseCommon, and v8_optimized_debug dependent settings go into DebugBase{0,1,2}

The new Debug configuration inherits from DebugBaseCommon and DebugBase<(v8_optimized_debug), while the new configuration Optdebug inherits from DebugBaseCommon and DebugBase2.
