Mythri 7629afdb9d [lite] Allocate feedback vectors lazily ... Allocate feedback vectors lazily when the function's interrupt budget has reached a specified threshold. This cl introduces a new field in the ClosureFeedbackCellArray to track the interrupt budget for allocating feedback vectors. Using the interrupt budget on the bytecode array could cause problems when there are closures across native contexts and we may delay allocating feedback vectors in one of them causing unexpected performance cliffs. In the long term we may want to remove interrupt budget from bytecode array and use context specific budget for tiering up decisions as well.
