engine didn't inline node's classIndex method because the switch statement in it wasn't inlineable.

Before:
RESULT heap-snapshot: _buildAggregates= 642 ms
RESULT heap-snapshot: _calculateClassesRetainedSize= 738 ms

After:
RESULT heap-snapshot: _buildAggregates= 335 ms
RESULT heap-snapshot: _calculateClassesRetainedSize= 411 ms
